Rear Cover Billet Big Bearing 6 Bolt

The PEM Rear Cover Billet Big Bearing 6 Bolt is a precision-engineered rear differential cover designed for high-performance vehicles that demand superior cooling and durability. Built from billet aluminum, this cover replaces standard stamped-steel factory units on differentials equipped with larger bearing assemblies. It is ideal for those running tuned engines or upgrading their drag-racing platforms.

Machined from solid billet stock rather than cast or stamped material, this rear cover offers superior structural rigidity and thermal conductivity compared to factory alternatives. The 6-bolt configuration provides a leak-free seal with substantial clamping force, critical when differential pressures rise during aggressive cornering or heavy towing loads. The "big bearing" designation indicates compatibility with heavy-duty bearing assemblies common in aftermarket differentials and limited-slip units.

This rear cover is suitable for mechanics and enthusiasts looking to enhance their vehicle's performance and reliability. It integrates seamlessly with existing differential housings, ensuring that it meets the demands of sustained performance driving. The cover is designed to maintain consistent gear oil viscosity under extreme conditions, making it a valuable addition to any performance vehicle.
