Dodge 2500 Differential Cover - Front - BD Diesel - BD Diesel AA 12-9.25 - 14-22. This BD Diesel front differential cover replaces the OE cover with a durable cast aluminum unit that adds cooling capacity and serviceability to the front differential of compatible Dodge/RAM trucks.

Constructed from cast aluminum with both internal and external cooling fins and a curved profile, this cover increases fluid surface area to help dissipate heat under load. It includes separate fill and drain ports with stainless steel plugs for easier servicing and a magnetic drain plug to capture metallic debris. The cover uses stainless steel Allen head cap bolts for secure fastening and is designed to work with aftermarket track bars. Capacity is approximately 2.7 quarts, and fitment targets AA 12-9.25 housings on RAM/Dodge 2500 (2014–2022) and 3500 (2013–2022).
