Bearing Buddy 2.408" Stainless Steel Trailer Wheel Bearing Protector, 2-Pack (42408)
Built for trailers that see regular saltwater or harsh outdoor exposure, the stainless steel Bearing Buddy delivers the same proven pressurized bearing protection as the original — with a full stainless steel barrel that outlasts chrome in corrosive environments. This model fits hubs with a 2.408" bore diameter and maintains positive grease pressure inside the hub cavity, actively blocking water, salt, and contaminants from reaching your bearings even after repeated submersion. A 2-pack covers both wheels on a single axle.

Parts Desk Insights
Best Use Case: The 2.408" bore is found on a range of mid-size boat and utility trailer axles. Choose stainless over chrome any time your trailer is regularly exposed to saltwater, brackish water, or high-humidity coastal conditions — the stainless barrel resists pitting and rust significantly longer. Always measure your hub bore before ordering. For closely related chrome options at a similar bore, see the 43401 chrome (2.401") or 43402 chrome (2.402"). For a larger stainless option, the 42444 stainless (2.444") and 42448 stainless (2.448") are the next sizes up. For trailers with drum brakes, pair with the Bearing Buddy Spindo Seal to complete the hub seal.
