Rear Main Cover Gasket - LS

The Rear Main Cover Gasket - LS from Chevrolet Performance is an OEM-specification replacement seal designed to prevent oil leakage at the rear main bearing housing on LS-series engines. This essential component is crucial for anyone involved in rebuilding, servicing, or restoring an LS-powered vehicle.

Constructed with a rubber and steel composite design, this gasket combines the durability of metal reinforcement with the sealing properties of engineered rubber. The steel backing provides structural support and resistance to warping under the thermal and mechanical stresses of engine operation, while the rubber facing ensures a compliant, oil-resistant seal against the mating surfaces of the rear cover and block.

This gasket is ideal for engine builders, performance shops, and enthusiasts working on any LS-platform engine, including the LS1, LS2, LS3, LS9, and LSA variants found in Corvettes, Camaros, Silverados, and engine swap applications. Proper installation is straightforward when the rear main cover is removed, ensuring a reliable, oil-tight seal that protects your investment and maintains engine integrity.
