For a broad range of common 3,500 lb trailer axles, I’d start with the GREPSPUD 5×4.5 Trailer Hub Kit, which combines hub and bearing components in one package. The DEEPDREAM 4-Set Bearing Kit stands out for buyers who want multiple bearing sets, while the iBroPrat Boat Trailer Kit is the specific-use option for boat-trailer maintenance. The main tradeoff is fit: axle capacity alone does not confirm bearing compatibility, so spindle dimensions and bearing numbers matter. Kits also differ in whether they include hubs, seals, dust caps, and enough sets for your repair. Read on for the full comparison and the checks I’d make before ordering.

Key Takeaways
- Fit outweighs kit quantity: The lineup includes distinct 1-inch, 1-1/16-inch, and #84 spindle applications, so matching bearing numbers and spindle measurements matters more than choosing the largest pack.
- Hub kits and bearing kits serve different jobs: GREPSPUD and ikkwmei include hub-focused components, while most other picks are bearing or bearing-and-seal replacement kits.
- Several 3,500 lb options overlap: DEEPDREAM, Niuohoy, and the L68149/L44649 kits target similar axle applications; their included seals, caps, and set counts help separate them.
- Small-axle owners have dedicated choices: FUSHIBEARING and the KABOBEARING set target 1-inch and 1-1/16-inch applications, unlike the many #84 spindle kits.
- Boat-trailer use calls for a use-specific match: iBroPrat is explicitly presented for boat trailers, but buyers still need to verify spindle fit and follow suitable inspection and maintenance practices.

More Details on Our Top Picks
GREPSPUD 5×4.5 Trailer Hub Kit for 3,500 lb Axles
This is the clearest choice when the job calls for replacing the hubs as well as their bearings. The pair of 5-on-4.5-inch idler hubs comes with bearings, seals, lug nuts, and extra caps and plugs, so it covers more of the repair than the bearing-only DEEPDREAM kit. Its fit is narrow, though: it is specified for 3,500 lb #84 EZ-Lube tapered spindles, not straight spindles, and the bearing dimensions should match the existing setup before ordering. The coated hubs and zinc-plated caps add corrosion resistance, a useful detail for trailers exposed to wet conditions, but they do not remove the need for routine inspection. Dust caps may need tapping into place during installation, so this is less appealing to anyone seeking a quick bearing-only service.
Pros:- Includes two hubs, bearings, seals, lug nuts, and installation-related hardware.
- Spare dust caps and rubber plugs provide replacement parts for later service.
- Coated steel hubs and zinc-plated caps are designed to resist corrosion.
- Specifies bearing and seal dimensions to help buyers check fit.
Cons:- Limited to compatible #84 EZ-Lube tapered spindles; not for straight spindles.
- Dust caps may need tapping into place during installation.
- Replaces more components than necessary for a bearing-only repair.
Best for: Trailer owners replacing both hubs on a 3,500 lb trailer with compatible #84 EZ-Lube tapered spindles and a 5-on-4.5-inch bolt pattern.
Not ideal for: Owners with straight spindles, a different bolt pattern, or hubs that only need fresh bearings and seals.
- Axle capacity:3,500 lb
- Spindle compatibility:#84 EZ-Lube tapered spindle; not for straight spindles
- Bolt pattern:5 on 4.5 in
- Outer bearing:L44649, 1-1/16 in inner diameter
- Inner bearing:L68149, 1-3/8 in inner diameter
- Grease seal:2.56 in outer diameter, 1.72 in inner diameter
- Included:Two hubs, hardware, two extra dust caps, and four rubber plugs
- Lug nut thread:1/2-20
Our verdict“Choose this kit when you need a matched pair of complete hubs for the stated 3,500 lb #84 EZ-Lube setup, not just replacement bearings.”
FUSHIBEARING Trailer Wheel Hub Bearing Kit for 1-Inch Axles
For a trailer built around a 1-inch axle, this kit supplies a defined bearing set rather than the larger L44649/L68149 combination used by the GREPSPUD and DEEPDREAM 3,500 lb options. It includes four L44643 bearings, four L44610 bearings, two seals, cotter pins, and dust covers, giving a repairer multiple bearing pairs while keeping the package focused on hub service. The tapered roller design and stamped steel cages are intended to limit friction, vibration, and noise; those details matter most when the bearing numbers and hub dimensions already match. Its main limitation is fit: the stated axle size does not make it interchangeable with 1-1/16-inch or 3,500 lb #84 setups. Buyers should verify their existing bearing numbers and seal dimensions before choosing it.
Pros:- Includes four L44643 and four L44610 tapered roller bearings.
- Supplies seals, cotter pins, and dust covers alongside the bearings.
- Alloy steel construction is specified for the bearing set.
- Stamped steel cages are intended to reduce friction, vibration, and noise.
Cons:- Fit is limited to matching 1-inch axle and hub dimensions.
- Does not include hubs, so it cannot replace a damaged hub assembly.
- The stated axle size alone is not enough to confirm fit; bearing and seal dimensions need checking.
Best for: Owners servicing trailer hubs specified for 1-inch axles who want bearings, seals, cotter pins, and dust covers in one package.
Not ideal for: Owners of 3,500 lb #84 axles or hubs requiring L44649/L68149 bearings, since this kit is specified for a 1-inch axle.
- Axle size:1 in
- Bearing numbers:L44643/L44610
- Bearing type:Tapered roller
- Inner diameter:1.000 in
- Outer diameter:1.980 in
- Bearing width:0.580 in
- Seal:12192TB, 1.980 in outer diameter
- Package contents:Four L44643 bearings, four L44610 bearings, two seals, two cotter pins, and two dust covers
Our verdict“Pick this for a matching 1-inch axle bearing service, but choose a different kit for the larger #84 and 3,500 lb bearing sizes.”
1-1/16” Axles Trailer Wheel Hub Bearings Kit L44649/L44610 | ID 1.0625″, OD 1.98″, Width 0.56″, 12192TB Seal, Dust Cover & Cotter Pin for 1-1/16” Axles Kit 2 Set
This kit is aimed at a specific middle ground: hubs using L44649/L44610 bearings on a 1-1/16-inch axle, rather than the 1-inch L44643/L44610 arrangement in the FUSHIBEARING kit. Its two sets include four bearings, two 12192TB seals, cotter pins, and dust covers, making it a practical choice for servicing both sides when those dimensions match. The listing gives an inner diameter of 1.0625 inches, a 1.98-inch outer diameter, and a 0.56-inch width, which helps with comparison against existing parts. Unlike the GREPSPUD kit, it supplies no hubs, and its stated fit should not be stretched to other axle sizes. The description promotes chrome steel and quiet rotation, but buyers should prioritize part-number and dimension matching over broad performance claims.
Pros:- Provides four L44649/L44610 bearings for two hub services.
- Includes two 12192TB seals, cotter pins, and dust covers.
- Lists bearing inner diameter, outer diameter, and width for fit checks.
- Chrome steel bearings and stamped cages are described in the product details.
Cons:- Does not include replacement hubs.
- Specified for 1-1/16-inch axles, so other axle sizes require a different kit.
- The supplied information does not identify an axle capacity or spindle model.
Best for: Owners repairing two trailer hubs that use L44649/L44610 bearings and a 1-1/16-inch axle with a matching 12192TB seal.
Not ideal for: Buyers replacing complete hubs or servicing 1-inch or #84 3,500 lb setups with different bearing and seal requirements.
- Axle size:1-1/16 in
- Bearing numbers:L44649/L44610
- Inner diameter:1.0625 in
- Outer diameter:1.98 in
- Bearing width:0.56 in
- Seal:12192TB
- Quantity:Two sets; four bearings total
- Included hardware:Two seals, two cotter pins, and two dust covers
Our verdict“Choose this two-set kit for dimension-matched 1-1/16-inch axle repairs when the hubs themselves remain serviceable.”
DEEPDREAM 4-Set Trailer Wheel Bearing Kit for 3,500 lb Axles
Among these options, DEEPDREAM is the bulk-service pick: four bearing sets and 40 parts suit owners maintaining several hubs or keeping spares on hand. It targets 3,500 lb axles with #84 spindles and includes L68149 and L44649 bearings, races, double-lip seals, spindle nuts, washers, cotter pins, dust caps, and plugs. That is a broader service bundle than the two-set bearing package in product 5, though, unlike GREPSPUD, it does not replace the hubs themselves. Chrome steel bearings and double-lip seals are intended to support smooth rotation and limit grease leaks, but fit still depends on matching the spindle and seal dimensions. The tradeoff is quantity: a single-trailer owner may have more parts than needed, and the product details do not provide installation instructions.
Pros:- Four sets provide bearings and service hardware for multiple hub repairs.
- Includes races, seals, spindle nuts, washers, cotter pins, dust caps, and rubber plugs.
- L68149 and L44649 bearing sizes match the stated #84, 3,500 lb application.
- Double-lip seals are intended to help reduce grease leakage.
Cons:- Limited to the listed bearing sizes and compatible #84 spindles.
- Does not include replacement hubs.
- Product details do not provide installation instructions.
- Four sets may be unnecessary for a one-hub repair.
Best for: Owners of 3,500 lb trailers with #84 spindles who service multiple hubs or want complete bearing-service sets in reserve.
Not ideal for: A buyer servicing just one hub, replacing damaged hubs, or working with a spindle other than the specified #84 type.
- Axle capacity:3,500 lb
- Spindle compatibility:#84
- Bearing sizes:L68149 (1-3/8 in) and L44649 (1-1/16 in)
- Seal:171255TB, 1.72 in inner diameter and 2.56 in outer diameter
- Dust cap diameter:1.98 in
- Kit quantity:Four sets, 40 pieces total
- Bearing material:Chrome steel
- Bearing type:Roller bearing
Our verdict“Choose DEEPDREAM for repeated or multi-hub service on compatible 3,500 lb #84 axles, not for a single repair or hub replacement.”
2 Pack Trailer Bearings Kit, High Speed and Rotary Quiet, L68149 L44649 Trailer Axle Bearings Kit, Fits for 1-3/8” to 1-1/16” 3500 Lbs Trailer Axle 1.719” Grease Seal 10-19#84 Spindle
This two-pack is a more focused alternative to DEEPDREAM’s four-set bundle for owners servicing a pair of hubs on a 3,500 lb #84 spindle. It lists L68149/L68111 and L44649/L44610 bearings, two 171255TB seals, and cotter pins, with the seal described as 1.719 inches. That makes the stated application similar to DEEPDREAM’s, but the smaller quantity may suit a routine two-hub repair better than stocking four sets. Unlike GREPSPUD, it contains bearings and seals rather than complete replacement hubs. The listing claims quiet operation and leak resistance from double-lip seals, yet it provides fewer dimensional details than some alternatives, so verify bearing numbers and seal fit against the parts being replaced before ordering.
Pros:- Two sets are sized for a paired hub service without the four-set quantity of DEEPDREAM.
- Lists L68149/L68111 and L44649/L44610 bearing numbers.
- Includes two 171255TB seals and two cotter pins.
- States compatibility with 3,500 lb trailer axles and #84 spindles.
Cons:- Does not include hubs, dust caps, or the broader hardware listed in DEEPDREAM’s kit.
- Product details provide limited bearing and seal dimensions for fit verification.
- Fit is restricted to the stated 3,500 lb #84 application.
Best for: Owners servicing two hubs on a 3,500 lb trailer with a compatible #84 spindle who do not need spare sets for future repairs.
Not ideal for: Buyers who need complete hub assemblies, four sets for multiple repairs, or more detailed dimensional data before confirming fit.
- Axle capacity:3,500 lb
- Spindle compatibility:#84
- Bearing numbers:L68149/L68111 and L44649/L44610
- Seal:171255TB
- Seal inner diameter:1.719 in
- Kit quantity:Two sets
- Included hardware:Two seals and two cotter pins
Our verdict“Pick this for a two-hub bearing service on a matching 3,500 lb #84 axle when a four-set stock of parts would be excessive.”
iBroPrat 4-Set 3500 lb Boat Trailer Axle Bearing Kit
I’d choose the iBroPrat 4-set when one purchase needs to cover several compatible hubs or leave spares for later service. Its 40-piece package includes bearings and races plus dust caps, rubber plugs, spindle nuts, washers, and cotter pins, so it is more complete than the two-set Niuohoy kit. Double-lip seals are intended to help limit grease leakage, a useful detail for boat-trailer maintenance, though seal design cannot replace regular inspection and greasing. The tradeoff is fit: this is for 3,500 lb axles with #84 spindles and the listed bearing sizes, not a universal trailer kit. I’d verify the spindle and seal dimensions before ordering; buyers servicing only one hub may find the four-set quantity unnecessary.
Pros:- Four sets provide parts for multiple maintenance jobs
- Includes dust caps, rubber plugs, spindle nuts, washers, and cotter pins
- Double-lip grease seals are designed to help reduce grease leakage
- Lists both bearing and race numbers for fit checks
Cons:- Fit is limited to compatible #84 spindle dimensions and bearing sizes
- Four sets may be more parts than a single-hub repair requires
Best for: Boat-trailer owners maintaining multiple compatible 3,500 lb hubs or keeping complete #84 spindle service kits on hand.
Not ideal for: Owners with one hub to service, straight spindles, or axle and seal dimensions outside the listed #84 fit.
- Quantity:4 sets; 40 pieces total
- Axle capacity:3,500 lb
- Spindle type:#84
- Axle fit:1-1/16 to 1-3/8 inches
- Bearings:L68149 and L44649
- Races:L68111 and L44610
- Grease seals:171255TB; 1.719-inch inner diameter
- Dust caps:1.98 inches
Our verdict“Choose this kit for multiple compatible 3,500 lb hubs; pick the Niuohoy two-set kit if you need fewer complete service sets.”
Pack of 2 Trailer Axle Hub Wheel Bearing Kits L44643 L44610 | Fits for 1” 2000-2200 Lbs Trailer Axle, 12192TB Grease Seals OD 1.980”
This two-kit option serves a different trailer fit from the 3,500 lb #84 kits: it is specified for 1-inch axles rated for 2,000–2,200 lb. That makes its L44643 bearings and L44610 races the relevant starting point for owners matching those dimensions, while the iBroPrat and BQEC kits use different bearing numbers for #84 spindles. The package supplies two inner and two outer bearings with races, along with two 12192TB seals, enough for the stated two-kit setup. The listing gives less detail about included spindle hardware and dust caps than the iBroPrat kit, so I would not assume those parts are included. Verify bearing IDs and seal dimensions against the existing hub before purchase.
Pros:- Specified for 1-inch axles rated at 2,000–2,200 lb
- Includes inner and outer L44643 bearings and L44610 races
- Includes two 12192TB grease seals
- Two-kit quantity can cover a pair of hubs
Cons:- Not specified for the #84 spindle fit used by the iBroPrat and BQEC kits
- Listing does not identify dust caps or spindle hardware as included
- Seal and bearing fit should be checked against the hub before ordering
Best for: Owners of 1-inch trailer axles in the stated 2,000–2,200 lb range who need bearing-and-race replacements for two hubs.
Not ideal for: Owners of 3,500 lb #84 axles or buyers seeking a kit that explicitly includes dust caps and spindle hardware.
- Axle fit:1-inch axle
- Axle capacity:2,000–2,200 lb
- Quantity:2 kits
- Bearings:L44643
- Races:L44610
- Grease seals:12192TB; 1.249 x 1.980 x 0.250 inches
- Seal outside diameter:1.980 inches
- Bearing and race count:2 inner and 2 outer bearings; 2 inner and 2 outer races
Our verdict“Pick this for a verified 1-inch, 2,000–2,200 lb axle bearing replacement, not as a substitute for a #84 spindle kit.”
2-Set Trailer Axle Bearing Kit for 3,500 lb Axles
The BQEC kit is aimed at routine service on 3,500 lb axles with tapered #84 spindles, with two complete sets of bearings, races, seals, caps, and spindle hardware. Its bearings are described as precision-engineered to reduce operating noise, making that a distinguishing stated benefit compared with the iBroPrat four-set kit, which puts more emphasis on quantity. Double-lip seals are also designed to limit grease leakage, while the included rubber plugs and hardware reduce the need to source small parts separately. The tradeoff is strict compatibility: the listing excludes straight, D-style, and grooved spindles. I’d match the bearing numbers and spindle style before ordering, then follow the recommended inspection and regreasing schedule rather than treating seals as maintenance-free.
Pros:- Two kits include bearings, races, seals, caps, and spindle hardware
- Bearings are described as designed to reduce operating noise
- Double-lip seals are intended to minimize grease leakage
- Lists bearing and race numbers for compatibility checks
Cons:- Not compatible with straight, D-style, or grooved spindles
- Only two kits, compared with the four included in the iBroPrat package
- Fit requires checking spindle style and dimensions before installation
Best for: Trailer owners servicing two 3,500 lb hubs with tapered #84 spindles who want a complete kit and value a design intended to reduce bearing noise.
Not ideal for: Owners with straight, D-style, or grooved spindles, or anyone who has not confirmed the #84 bearing and seal fit.
- Quantity:2 kits
- Axle capacity:3,500 lb
- Spindle type:#84 tapered spindle
- Bearing sizes:L68149, 1-3/8 inches; L44649, 1-1/16 inches
- Bearing and race numbers:L68149/L68111 and L44649/L44610
- Grease seals:2; 171255TB; 1.72-inch inner diameter
- Dust caps:2; 1.98 inches
- Included hardware:2 spindle nuts, 2 washers, 2 cotter pins, 4 rubber plugs
Our verdict“Choose BQEC for complete two-hub service on verified tapered #84 spindles; choose iBroPrat if you need four sets.”
Niuohoy Trailer Bearing Kit for 3,500 lb Axles, 2 Sets
Niuohoy offers a straightforward middle ground for owners who need two complete #84 bearing sets rather than the four supplied by iBroPrat. The 20-piece package includes inner and outer bearings and races, seals, spindle nuts, dust caps, plugs, washers, and cotter pins, so it covers more of a service job than a bearings-only replacement. Its listed chrome steel and NBR rubber materials and double-lip seals describe the construction, but the listing does not provide the noise-reduction claim featured by BQEC. Installation also has a small practical catch: the dust caps need careful mallet or hammer fitting. I’d confirm the 1-1/16- and 1-3/8-inch bearing fit and #84 spindle style first; this is not the choice for an axle using a different bearing arrangement.
Pros:- Two sets provide 20 listed parts for hub service
- Includes dust caps, rubber plugs, spindle nuts, washers, and cotter pins
- Chrome steel and NBR rubber construction is specified
- Double-lip seals are intended to help limit grease leaks
Cons:- Limited to compatible #84 spindles and listed bearing dimensions
- Dust caps require careful mallet or hammer installation
- Provides fewer sets than the iBroPrat four-set kit
Best for: Owners of compatible 3,500 lb #84 axles who want two complete service sets with caps and spindle hardware included.
Not ideal for: Owners needing four sets, a stated noise-reduction design, or bearings for straight spindles and other axle configurations.
- Quantity:2 sets; 20 pieces
- Axle capacity:3,500 lb
- Compatible spindle:#84; 1-1/16 to 1-3/8 inches
- Bearing numbers:L68149 and L44649
- Materials:Chrome steel and NBR rubber
- Grease seal design:Double lip
- Outside diameter:1.98 inches
- Compatible lubricant:Grease
Our verdict“Choose Niuohoy for two fully equipped #84 service sets; choose iBroPrat when you need parts for more hubs.”
ikkwmei 3500 lb Trailer Idler Hub Kit, 5 on 4.5 in Bolt Pattern, for #84 Tapered Spindles
Unlike the iBroPrat, BQEC, and Niuohoy products, which supply bearing-service parts, this ikkwmei package includes two complete idler hub assemblies. That makes it the more relevant choice when worn hubs need replacement along with the bearings, and the kit also includes lug nuts and installation hardware. Its 5-on-4.5-inch bolt pattern and #84 tapered-spindle fit are specific, so I’d match both the wheel pattern and spindle bearings before buying. The black rust-resistant coating is a useful finish detail, but this is an idler setup with no brakes; it is not a replacement for a braked hub assembly. It also will not fit straight spindles or axles using the same size inner and outer bearings, which makes its scope narrower than a bearing-only kit.
Pros:- Includes two complete idler hub assemblies, not just bearing-service parts
- Includes inner and outer bearings, seals, caps, lug nuts, and spindle hardware
- 5-on-4.5-inch bolt pattern is specified
- Black coating is described as rust-resistant
Cons:- Idler hubs have no brakes
- Not compatible with straight spindles or equal-size inner and outer bearings
- Requires matching both the spindle fit and wheel bolt pattern
Best for: Owners replacing both hub assemblies on a 3,500 lb trailer with #84 tapered spindles and a 5-on-4.5-inch wheel pattern.
Not ideal for: Owners who only need bearings, have straight spindles or equal-size inner and outer bearings, or require hubs with brakes.
- Capacity:3,500 lb
- Hub assemblies:2
- Bolt pattern:5 on 4.5 inches
- Spindle compatibility:#84 tapered spindles
- Outer bearing:L44649; 1-1/16 inches
- Inner bearing:L68149; 1-3/8 inches
- Brake type:Idler hub; no brakes
- Lug nut thread:1/2 in-20
Our verdict“Choose this when replacing complete unbraked hubs on a matching #84 trailer; choose a bearing kit if the existing hubs remain serviceable.”
Trailer Bearings Kit L68149 Bearing Kit L44649 Bearing Kit -2 Sets Compatible with 3500lbs 1-1/16” to 1-3/8” Trailer Axles, Spindle #84
This two-set package stands out for buyers who want more than the bearings and races: it also includes dust caps, rubber plugs, spindle nuts, washers, and cotter pins. That broader hardware selection makes it more complete than the Lwlusup two-pack, whose listed contents focus on bearings, races, seals, tang washers, and cotter pins. Both are aimed at compatible 3,500 lb #84 spindles with L68149 inner and L44649 outer bearings, so exact dimensions still need to match the trailer. The listing specifies EZ-Lube compatibility and separately sealed component bags, which can help keep spares organized. The tradeoff is that the product data gives fewer precise dimensions than Lwlusup’s listing, so buyers who need to verify measurements before ordering may prefer that more detailed option.
Pros:- Two sets include inner and outer bearings, races, and grease seals
- Adds dust caps, rubber plugs, spindle nuts, washers, and cotter pins
- Listed as compatible with 3,500 lb #84 and EZ-Lube axles
- Separate sealed bags support organized storage of components
Cons:- Product data does not provide the detailed bearing and race dimensions listed for the Lwlusup two-pack
- Fit is limited to the specified L68149/L44649 configuration and compatible spindle
- The listing does not specify the material for every included hub component
Best for: Owners of compatible 3,500 lb trailers who want two bearing sets plus hub hardware such as dust caps, plugs, nuts, and washers.
Not ideal for: Buyers who need clearly itemized bearing and spindle measurements before ordering, or whose trailer does not use the specified #84 spindle and bearing numbers.
- Axle capacity:3,500 lbs
- Spindle compatibility:#84; listed for EZ-Lube axles
- Inner bearing:L68149
- Outer bearing:L44649
- Inner race:L68111
- Outer race:L44610
- Grease seals:171255TB, 1.719-inch I.D.; 2 included
- Additional components:2 dust caps, rubber plugs, spindle nuts, washers, and cotter pins
Our verdict“Choose this kit if you have a matching 3,500 lb #84 axle and want two bearing sets with a wider assortment of hub hardware.”
Pack of 2 Trailer Axle Bearing Kits, L68149 and L44649
For shoppers who want to check axle fit by the numbers, this Lwlusup two-pack provides the clearest dimensional detail in this group: it lists bearing IDs, race ODs, seal size, and #84 spindle dimensions. That makes it easier to compare against existing parts than the two-set kit from B0CH9YZZVY, whose listing names the bearing family but supplies fewer measurements. Each kit includes inner and outer bearings and races, double-lip seals, tang washers, and cotter pins, covering the core replacement parts without the dust caps and plugs found in that more hardware-heavy alternative. Its scope is narrower, but the specifications make the compatibility check more deliberate. Buyers still need to confirm their actual spindle and hub dimensions; the 3,500 lb capacity alone does not establish fit.
Pros:- Lists bearing IDs, race ODs, seal details, and spindle dimensions
- Two kits provide inner and outer bearings, races, seals, washers, and cotter pins
- Double-lip grease seals are specified
- Designed for compatible 3,500 lb axles with #84 spindles
Cons:- Does not list dust caps, rubber plugs, or spindle nuts among the included components
- Fit depends on matching the listed bearing and spindle dimensions
- The product data identifies alloy steel but gives no further bearing construction detail
Best for: Trailer owners or repairers who can identify their #84 spindle and want explicit bearing, race, and seal measurements to check before buying.
Not ideal for: Buyers who need dust caps, plugs, spindle nuts, or washers in the package, or who cannot confirm the listed bearing dimensions against their axle.
- Brand:Lwlusup
- Part number:TABK-2SET
- Axle capacity:3,500 lbs
- Inner bearing and race:L68149, 1.378-inch ID; L68111, 2.362-inch OD
- Outer bearing and race:L44649, 1.063-inch ID; L44610, 1.980-inch OD
- Grease seal:171255TB (10-19), double lip; 1.719 x 2.565-inch spindle specification listed
- Included components:2 inner and 2 outer bearings, 2 inner and 2 outer races, 2 seals, 2 tang washers, 2 cotter pins
- Material:Alloy steel
Our verdict“Pick this two-pack when precise dimensions matter more than having dust caps and extra hub hardware in the box.”
Trailer Wheel Hub Bearing Kit for 1-Inch Axles, 2 Sets
This KABOBEARING set serves a different axle class from the L68149/L44649 kits: it is specified for 1-inch axles rated for 2,000–2,200 lbs, using L44643 bearings rather than the larger-dimension 3,500 lb bearing pair. That distinction matters more than the ABEC-3 label; a rating or material claim cannot make the wrong bearing size fit. The package contains four L44643 bearings, four L44610 races, seals, cotter pins, and dust covers for two hubs. Compared with the other KABOBEARING option here, which uses L44649 parts for 1-1/16-inch axles, this is the pick for trailers with the smaller specified axle dimensions. Its limitation is equally clear: it is not a general substitute for 3,500 lb #84 spindle kits.
Pros:- Specified for 1-inch axles rated for 2,000–2,200 lbs
- Two-hub package includes bearings, races, seals, cotter pins, and dust covers
- Uses tapered roller bearings in alloy steel
- Lists ABEC-3 as its bearing standard
Cons:- Fit is limited to the specified 1-inch axle and bearing dimensions
- Not suitable for the 3,500 lb L68149/L44649 axle setup
- Includes two seals and two cotter pins, so component quantities differ from the four-bearing and four-race counts
Best for: Owners of light-duty trailers with verified 1-inch axles and a 2,000–2,200 lb rating who need bearing parts for two hubs.
Not ideal for: Owners of 1-1/16-inch or 3,500 lb #84 axles, or anyone whose bearing numbers and dimensions do not match L44643.
- Brand:KABOBEARING
- Axle compatibility:1-inch axles; 2,000–2,200 lbs
- Bearing numbers:L44643 and L44610
- Bearing type:Tapered roller
- Bearing dimensions:1.000-inch inner diameter; 1.980-inch outer diameter; 0.580-inch width
- Seal:12192TB
- Material and standard:Alloy steel; ABEC 3
- Package contents:4 L44643 bearings, 4 L44610 races, 2 seals, 2 cotter pins, 2 dust covers
Our verdict“Choose this set for a verified 1-inch, 2,000–2,200 lb axle rather than a larger 3,500 lb trailer spindle.”
Trailer Bearings Kit L68149/ L44649 Bearing Kit Compatible with 3500lbs 1-1/16” to 1-3/8” Trailer Axles, Spindle #84 with 171255TB Grease Seals, Trailer Dust Caps -4 Sets
With four complete bearing sets, this package is aimed at servicing multiple hubs or keeping matched replacements on hand—not a one-hub repair. It shares the L68149 inner and L44649 outer bearing setup with the two-set B0CH9YZZVY kit, but doubles the listed component quantities, including seals, caps, plugs, nuts, washers, and cotter pins. That makes the larger pack more useful for a multi-hub job, while the smaller kit is the more restrained choice if only two sets are needed. Both are described for 3,500 lb axles and #84 spindles, including EZ-Lube applications. The tradeoff is that this package commits the buyer to four sets, and the listing does not give the detailed bearing and spindle measurements provided by the Lwlusup two-pack.
Pros:- Four inner and four outer bearings with matching races and seals
- Includes four each of dust caps, rubber plugs, spindle nuts, washers, and cotter pins
- Listed for 3,500 lb axles, #84 spindles, and EZ-Lube axles
- Chrome steel bearings are specified
Cons:- Four sets may exceed the needs of a single-hub or two-hub repair
- Product data omits detailed bearing and spindle measurements
- Compatibility depends on the L68149/L44649 bearing configuration
Best for: Trailer owners, fleet maintainers, or repair shops preparing to service several compatible 3,500 lb #84 axle hubs.
Not ideal for: Anyone replacing only one or two hub sets, or buyers who need detailed dimensions to verify compatibility before ordering.
- Axle capacity:3,500 lbs
- Spindle compatibility:#84; listed for EZ-Lube axles
- Inner bearing:L68149; 4 included
- Outer bearing:L44649; 4 included
- Races:L68111 and L44610; 4 of each included
- Grease seals:171255TB, 1.719-inch I.D.; 4 included
- Additional components:4 dust caps, rubber plugs, spindle nuts, washers, and cotter pins
- Bearing material:Chrome steel
Our verdict“Choose this bulk package when several compatible #84 hubs need service; for a smaller job, the two-set B0CH9YZZVY kit is the closer match.”
KABOBEARING Trailer Wheel Hub Bearing Set for 1-1/16-Inch Axles
This KABOBEARING set is for a narrower fit than the 3,500 lb L68149/L44649 kits: it uses L44649 and L44610 parts for 1-1/16-inch axles, with a listed bearing ID of 1.0625 inches. Its package supplies four bearings and four races, plus two seals, cotter pins, and dust covers. That makes it a useful two-hub parts set when those exact numbers match, while the other KABOBEARING option in this roundup is intended for 1-inch axles and L44643 bearings. The description calls these ball bearings, so buyers should confirm the component type and part numbers against their existing hub rather than relying only on axle diameter. Compared with the four-set 3,500 lb kit, this option is more targeted and does not include a matching L68149 inner-bearing set.
Pros:- Includes four L44649 bearings and four L44610 races
- Package also includes seals, cotter pins, and dust covers
- Lists a 1.0625-inch bearing ID and 1.9800-inch outer diameter
- Alloy steel construction and ABEC-3 specification are stated
Cons:- Compatibility is limited to the specified 1-1/16-inch axle setup
- Does not include L68149 inner bearings for the paired 3,500 lb configuration
- Listing identifies the bearings as ball bearings, so buyers should verify type against their hub parts
Best for: Owners of trailers with verified 1-1/16-inch axles using L44649/L44610 components who need parts for two hubs.
Not ideal for: Buyers with 1-inch axles, 3,500 lb #84 setups requiring L68149 inner bearings, or hubs that need a different seal or bearing type.
- Brand:KABOBEARING
- Compatibility:1-1/16-inch trailer axles
- Bearing numbers:L44649 and L44610
- Bearing dimensions:1.0625-inch ID, 1.9800-inch OD, 0.56-inch width
- Seal:12192TB
- Material and specification:Alloy steel; ABEC 3
- Compatible lubricant:Grease
- Included components:4 L44649 bearings, 4 L44610 races, 2 seals, 2 cotter pins, 2 dust covers
Our verdict“Pick this set only when your 1-1/16-inch hub calls for L44649/L44610 parts and its seal dimensions also match.”
How We Picked
I organized these options by fit clarity, what the kit includes, and the repair task each one appears designed to handle. A clearly stated bearing number, spindle size, seal dimension, axle application, or hub bolt pattern helps reduce the chance of ordering parts that do not match. I also separated complete hub-oriented kits from bearing-only replacements, since they solve different problems and cannot be treated as direct substitutes.
The ranking favors options with a clearly described use case and useful inclusion details, then distinguishes them by axle type, number of sets, and stated specialty. A multi-set package can suit planned maintenance, but it ranks below a better-defined fit when compatibility is unclear. Product titles do not establish material quality, service life, or exact contents beyond what they state, so I would verify the listing and compare its dimensions with the existing parts before buying.
Factors to Consider When Choosing Wheel Bearings Trailer
Trailer bearing selection starts with the parts already on your axle, not a broad label like “3,500 lb.” I use these checks to narrow the field, avoid common fit errors, and decide when a more complete kit is worth choosing.
Match Bearing Numbers and Spindle Dimensions
Start by identifying the numbers stamped on the existing inner and outer bearings; examples in this roundup include L44649, L44610, L44643, and L68149. If the markings are unreadable, measure the spindle at the bearing seats with a suitable measuring tool and compare those dimensions with the replacement specifications. A stated axle capacity is only a starting point because different spindles and bearing combinations can appear on trailers with similar ratings. Do not assume that a 1-inch or 1-1/16-inch description refers to every relevant dimension in the assembly. Check both bearings, the seal, and the spindle style before ordering. This extra check is more reliable than choosing a kit based on a general vehicle or trailer description.
Choose a Bearing Kit or a Hub Kit
A bearing kit is generally aimed at servicing the rotating components, while a hub kit can include the hub itself and may suit a different repair scope. The GREPSPUD and ikkwmei listings are hub-focused, so compare their hub pattern and spindle compatibility with the trailer rather than treating them as bearing-only alternatives. If the hub is sound and only bearings or seals need replacement, a bearing kit may avoid buying parts you do not need. If the hub is damaged or the repair calls for a complete assembly, a hub kit may be more appropriate. Confirm exactly which parts are included because product titles can group components differently. Replacing a hub does not remove the need to verify its bearing and seal fit.
Read Seal and Dust-Cap Details Alongside Bearing Fit
Seals and dust caps are easy to overlook when comparing bearing numbers, yet they affect whether a service kit covers the parts you plan to replace. The listings in this roundup cite different seal specifications, including 12192TB and 171255TB, so check the seal number and dimensions against the old seal or hub. A seal that looks similar may still have a different outer diameter or sealing profile. Dust caps and cotter pins also vary by package, and their inclusion can save a separate parts search if they are needed for the job. Do not assume every multi-piece bearing kit contains the same accessories. Make a short checklist of worn parts before deciding whether an expanded package is useful.
Buy the Set Count That Matches the Repair
Package size should reflect how many hubs you are servicing and whether you want spare components, not simply which listing contains the most sets. A two-set kit may cover a paired repair depending on its exact contents, while four-set listings may suit multiple hubs or planned replacement work. Verify what the seller means by a “set,” since the word can describe a pair of bearings or a larger assortment. Buying extra parts is less helpful if the bearing specification is wrong or the package omits the seal you need. For one damaged hub, compare the parts count with your repair list before choosing a larger pack. For fleet or repeat maintenance, confirm that the same fit applies across every trailer in the group.
Treat Axle Rating as a Filter, Not Proof of Compatibility
Several products here are labeled for 3,500 lb axles, but that label alone does not confirm that they fit a particular trailer. The lineup also includes kits for 1-inch axles, 1-1/16-inch axles, 2,000–2,200 lb applications, and #84 tapered spindles. Use the axle rating to narrow candidates, then confirm the bearing pair, spindle, hub, seal, and bolt pattern where applicable. This is especially relevant when comparing a complete hub with a bearing-only kit, since the hub adds another compatibility check. If the trailer’s documentation and existing parts disagree, pause and identify the actual spindle configuration before ordering. A correctly matched part is a better starting point than a broad capacity match.
Set Expectations for Boat-Trailer Service
A boat-trailer-specific label, such as the one on the iBroPrat kit, can help focus the search, but it does not by itself establish suitability for every marine setup. Verify the bearing and seal dimensions as carefully as you would for a utility trailer, and check whether the package includes the parts your service plan requires. Regular exposure to water makes inspection and correct maintenance especially relevant, but no kit title should be read as a guarantee against water intrusion or corrosion. Ask whether the product details identify materials or protective features if those matter for your conditions. Consider how often the trailer is immersed and how it is maintained when choosing between a standard replacement kit and a specifically labeled boat-trailer option. Fit remains the first check; intended use is an additional filter.
Frequently Asked Questions
Can I choose a trailer bearing kit by axle weight alone?
No. Axle capacity narrows the options, but it does not identify the bearing numbers, spindle dimensions, seal, or hub configuration on your trailer. This roundup includes multiple 3,500 lb applications as well as smaller axle choices, showing why one capacity label does not cover every fit. Check the numbers stamped on the old bearings and compare the seal and spindle details with the product listing. If those markings are missing, measure the spindle carefully or consult the trailer or axle documentation before ordering.
What should I check if my old bearing numbers are unreadable?
Clean the bearing enough to inspect for markings, then measure the spindle at the inner and outer bearing seats with an appropriate precision measuring tool. Record the seal location and dimensions as well, since the seal must match the hub and spindle arrangement. Compare those measurements with the candidate kit’s stated inner diameter, outer diameter, width, and seal details where provided. Avoid relying on a visual match or the trailer’s model year alone. If measurements remain uncertain, take the old parts to a trailer-parts specialist for identification.
Should I buy a hub kit or just a bearing kit?
Choose a bearing kit when the hub is serviceable and the repair is limited to bearings, seals, or related small parts. A hub kit makes more sense when the hub itself needs replacement or when you want a package intended to cover a broader assembly. In this roundup, GREPSPUD and ikkwmei are hub-focused options, while most entries are bearing kits, so compare the repair scope before comparing package size. Check the hub’s bolt pattern, spindle fit, and included components rather than assuming a hub package fits because its axle rating is familiar. Reuse a sound hub only if it is appropriate for the repair and has been inspected.
Do four-set kits fit every 3,500 lb trailer?
No. A larger set count describes package quantity, not universal compatibility. Several four-set listings target 3,500 lb applications, but the required bearing pair, spindle type, and seal can still differ from one trailer to another. Confirm what each listing counts as a set and whether its bearing numbers match your old parts. If you are servicing only one hub, a larger package may leave you with unused components without solving a fit mismatch. Buy the quantity that suits the repair only after confirming the application.
Is a boat-trailer bearing kit automatically better for a trailer used in water?
Not automatically. A boat-trailer label can identify an intended use, but it does not prove the kit fits your spindle or includes every part your maintenance plan needs. Check the bearing numbers, seal specifications, and stated contents, then compare them with your existing hub. Water exposure also makes correct installation and ongoing inspection important, and a product title alone cannot promise protection from water or corrosion. The iBroPrat listing is the roundup’s explicitly boat-focused option, but fit and documented specifications should decide whether it suits your trailer.
Conclusion
For the best overall starting point among these listings, I’d shortlist GREPSPUD when you need a 3,500 lb hub kit with a 5×4.5 bolt pattern and have confirmed the fit. For multi-set value, compare DEEPDREAM, Niuohoy, and the four-set L68149/L44649 kits by exact bearing and seal contents rather than package size alone. I’d treat a specifically described package with clear bearing numbers as the best choice for beginners, since it is easier to verify against old parts. For a premium or broader repair, favor a hub kit only when replacing the hub is part of the job; no listing here establishes a quality tier from its title alone. Owners of 1-inch or 1-1/16-inch axles should focus on the FUSHIBEARING, KABOBEARING, and other size-specific kits, while boat-trailer owners can start with iBroPrat and confirm all dimensions. My final recommendation is to match bearing numbers, spindle measurements, and seal details before choosing any kit.
