Crane Axle Super Duty Unit Bearing Covers are designed to protect 2005 and newer Ford Super Duty unit bearings from mud, water, sand, and debris encountered in harsh off-road environments. Built specifically for applications using 32 spline stub axles such as RCV Big Bell setups, these covers help maintain bearing lubrication while adding an additional layer of protection to the hub assembly.

Precision machined from 6061 aluminum and finished with a black anodized coating, these covers are built for long-term durability and corrosion resistance. The integrated O-ring sealing system helps keep grease contained inside the hub while limiting contamination entry during trail use, water crossings, and high-abuse off-road driving. Designed for direct fitment on 2005+ Ford Super Duty unit bearings, they install using the included stainless hardware.

Tech Insight 

Off-road driving environments introduce mud, sand, and water that can rapidly damage unit bearings if left unprotected. These precision-fit bearing covers act as a barrier against debris, maintaining lubrication and extending bearing life. The 6061 aluminum construction and anodized finish ensure corrosion resistance and strength, while the O-ring seal keeps grease where it belongs — inside your hub. Whether you’re rock bouncing or trail running, these covers keep your Super Duty bearings performing at their best.
