GM LS Engine Timing Cover Gasket Set

The GM LS Engine Timing Cover Gasket Set by Racing Power Co-Packaged is a complete seal replacement kit engineered for LS-series small-block engines. This precision gasket set addresses one of the most critical fluid containment points in modern LS architecture—the timing cover interface—where oil seepage can compromise engine cleanliness and longevity during high-performance operation, street driving, or long-term storage.

Constructed from a hybrid aluminum and rubber material composition, the gasket set delivers a 0.065-inch thickness engineered to match OEM specifications while maintaining conformability across the irregular surfaces of LS timing covers. This thickness is critical: too thin and the gasket fails to seal under thermal cycling; too thick and clamping force becomes insufficient, resulting in oil weeping at idle or light load conditions. The aluminum core provides dimensional stability and heat resistance, while the rubber elastomer layer ensures a dynamic seal that accommodates the expansion and contraction cycles inherent in engine operation, particularly during temperature swings between cold starts and sustained highway cruising.

This gasket kit is essential for LS engine builders, restoration shops, and enthusiasts performing timing cover removal for cam swap work, front cover repair, or complete engine rebuilds. Whether you're installing a crate LS engine in a classic car chassis, rebuilding a stock LS after high-mileage service, or assembling a performance package, a quality timing cover gasket set prevents the oil seepage that can attract dust, degrade bay appearance, and signal deeper issues. Racing Power Co-Packaged components are widely specified in professional engine shops because they meet or exceed OEM quality standards at competitive pricing, making them a trusted choice for both stock and modified applications.
