Product Details

Rear Differential Cover by B&M®. Finish: Black Anodized. Material: A356.0-T6 Aluminum. B&M Cast Aluminum Differential Covers are designed to strengthen the differential by preventing case distortion and ring gear & bearing cap deflection. Constructed of A356.0-T6 aluminum, these rugged covers significantly increase the fluid capacity and dissipate heat much faster than the stock factory unit to prolong the life of your ring and pinion gears. Additional features include an engraved B&M logo, drain and fill port locations, a magnetic drain plug for catching ferrous metal particles, and complete hardware and installation instructions.

B&M has always been the choice for performance and dependability. Racers themselves, B&M’s founders identified the needs of local racers and street performance enthusiasts around the world, and developed products to fill as many needs as possible. All B&M products are extremely robust and will endure the test of time to give you the most for your money. Whether you have a damaged, broken, or lost part, B&M got a comprehensive collection of replacements to restore the effective operation of your B&M shifter. All parts are designed to ensure a precise fit and they’re fairly easy to install. Besides, they are waiting for you at a price that everyone can afford!
