The B&M Cast Aluminum Differential Cover was designed to strengthen the rear end by preventing case distortion, ring gear and cap bearing deflection. Constructed of A356.0-T6 aluminum, this rugged unit dissipates heat much faster than the stock factory unit to prolong the life of your ring and pinion gears. To increase durability and aesthetics without compromising heat dissipation, the cover has been coated with a U.S. military-grade (MIL-A-8625) black anodized finish. Additional features include an engraved B&M logo, added fluid capacity for better cooling, magnetic drain plug for catching ferrous metal particles, complete hardware, installation instructions and a one-year warranty.
