Dependable Trailer Hub Replacement

Your boat trailer's wheel hubs are essential to safe and smooth towing. They support the trailer wheels while allowing them to rotate around the axle spindle.

Over time, exposure to water, road debris, and repeated towing can contribute to bearing wear, grease seal deterioration, and hub damage.

The C.E. Smith 13316 Hub Kit is designed to help restore dependable wheel hub operation when properly installed on a compatible axle assembly.
