Ultra durable

Made from military grade aluminum

The B&M black anodized differential cover is manufactured from A356.0-T6 aluminum and is designed to strengthen your rear differential by preventing case distortion. This unit also dissipates heat much faster than the original or other powder coated aluminum covers due to the 0.4 quart added fluid capacity and finned construction. Features include a large B&M engraved logo, and a magnetic drain plug for good looks and easy services. This cover comes complete with installation hardware and instructions. Correct for GM 8.2", 8.5", and 8.6" ten bolt differentials.
