Dodge 3500 Differential Cover - Front - BD Diesel - BD Diesel AA 12-9.25 - `13-`22 is a cast aluminum front differential cover designed for RAM 3500 models (2013–2022). It provides improved cooling capacity and easier servicing compared with a stock cover while maintaining compatibility with common aftermarket components.

This BD Diesel front diff cover features internal and external cooling fins and a curved profile that increases fluid surface area for heat dissipation. The cover includes separate fill and drain ports with stainless steel plugs for convenient fluid changes and service, and comes with stainless steel Allen head cap bolts plus a magnetic drain plug to help capture metal particles. It increases total differential fluid capacity to 2.7 quarts and is designed to fit the AA 12-9.25 differential and work with aftermarket track bars where applicable.
