Dexter 3500 lb Trailer Bearing Kit vs 3.5K Trailer Bearing Kit

Both kits service one 3,500 lb hub with the same bearing set: L44649 outer, L68149 inner, L44610 and L68111 races, and a 1.719 in ID double lip seal. The Dexter kit adds a dust cap with plug, spindle retainer and cotter pin, and is the safer pick if you want a complete one-box rebuild. The MAT kit is the same core hardware under part number BEK-3.5K, so choose it if you already have a good cap and spindle hardware. Owners of the Dexter kit report good fit and quality, with the main complaint being an outer bearing that is too small on 6,000 lb axles, so confirm your axle rating before ordering.

• Choose the Dexter 3500 lb Trailer Bearing Kit if you want bearings, races, seal, dust cap, retainer and cotter pin in one box for a full hub rebuild.
• Choose the 3.5k Bearing kit (MAT) if you only need the bearings, races and seal and already have a serviceable cap and spindle hardware.
