The B&M Cast Aluminum Rear End 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 also dissipates 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, added fluid capacity for better cooling, magnetic drain plug for catching ferrous metal particles, complete hardware, installation instructions and a one year warranty.
