3.5K Trailer Bearing Kit vs WPS Trailer Bearing Kit #1149

These two kits fit the same hub: both use L44649 outer and L68149 inner bearings with L44610 and L68111 races on a #84 spindle for 3,500 lb axles. The real split is contents. Kit A adds a dust cap and sometimes grease or a grease fitting, so it covers more of the job in one box. Kit B is a tighter, known package with a spring-loaded double lip seal and a 4.8 rating from 84 owners. Buy A for a fuller service kit; buy B if you already have caps and want the better seal.

• Choose the 3.5K Bearing kit (MAT) if you want a dust cap and possibly grease or a fitting included so one box covers the whole hub service.
• Choose the WPS #1149 kit if you already have dust caps and want a spring-loaded double lip seal with a strong owner rating.
