3.5K Trailer Bearing Kit vs Lippert Bearing Replacement Kit 2023133980

These two kits are functionally the same part set: L44649 outer bearing, L68149 inner bearing, L44610 and L68111 races, and a 1.719-inch ID seal for a 3,500 lb axle hub. The Lippert kit is the safer pick if you want a branded, well-documented set with a double-lip seal and a stated install time; the generic 3.5K kit is the pick if you already know your spindle is a #84 and you just want the standard parts. Owners of both report the same fit and finish on 3,500 lb hubs, and the 4.5-star rating on the generic kit reflects that these are commodity parts. Neither is a step up in durability over the other; buy on seal type and included hardware.

• Choose the 3.5K Bearing kit if you have confirmed a #84 spindle and want the plain standard kit with a 10-172 seal.
• Choose the Lippert kit if you want a branded set with a double-lip seal, cotter pin and tang washer spelled out.
