4.200 MLX Head Gasket RH .052 GM LSX

The 4.200 MLX Head Gasket RH .052 GM LSX from Cometic Gaskets is a premium sealing solution specifically engineered for high-performance GM LSX engine builds. This right-hand gasket is ideal for serious engine builders, performance shops, and automotive enthusiasts who require reliable and durable components for their builds.

Designed with a .052-inch thickness, this gasket features Cometic's MLX composite construction, which combines a proprietary elastomer blend with embedded steel wire. This innovative design allows for effective sealing without relying on soft copper facings that can compress over time. The 4.200 inches bore diameter ensures precise coverage for the LSX engine family, minimizing the risk of hot-spot leakage.

Engine builders working on naturally aspirated, supercharged, or turbocharged LSX applications will benefit from the gasket's ability to maintain clamp load retention through thermal cycling. Using the correct right-hand (RH) orientation is crucial for V8 applications, as it prevents cross-fire leakage between adjacent cylinders and supports proper coolant circulation.
