Bearing Buddy 43105 2.328" Chrome Wheel Bearing Protector with Bra

The Bearing Buddy 43105 is a chrome-plated wheel bearing protector designed for trailer hubs with a 2.328-inch (approximately 2-5/16-inch) inside diameter bore. It replaces the standard dust cap and keeps the hub filled with grease under positive pressure, preventing water and dirt from entering the bearings—even when submerged during boat launching and retrieval.

An automatic pressure relief system vents excess grease if the hub is overfilled, protecting seals from damage. The included Bearing Buddy Bra is a vinyl cover that fits snugly over the protector to catch any excess grease and keep it off your tires and wheels.
