      Enhanced Cooling Performance. The BD Power AA14-11.5 Rear Differential Cover in Black is engineered to improve lubrication and cooling within the differential by redirecting oil onto critical gear components.

It features a sleek black finish, stainless steel Allen head cap bolts, a fill plug, and a gasketless design with an integral reusable Viton O-ring, ensuring a secure, clean, and corrosion-resistant installation.

      Installation. Installation is straightforward, requiring approximately 30 minutes with no drilling needed, making it accessible for both professional mechanics and DIY enthusiasts.

      Warranty. This product comes with a 36-month/150,000-mile warranty, providing peace of mind and guaranteed quality.

      Application. Specifically designed to fit the 2007-2019 6.6L Duramax Sierra 3500 HD and compatible Dodge (2003 and newer) and Chevy (2001 and newer) models with the AA14-11.5 differential, ensuring precise fit and optimal performance.
