4.150 MLX Head Gasket .052 GM LSX Race RH

The Cometic Gaskets 4.150 MLX Head Gasket .052 GM LSX Race RH is a precision-engineered cylinder head gasket designed for high-performance and racing applications on GM LS-series engines. Built with multi-layer steel construction, this right-hand gasket delivers reliable sealing under extreme combustion pressures and elevated engine temperatures typical of forced-induction and naturally aspirated racing environments.

The 4.150-inch bore diameter and 0.052-inch compression thickness are precisely calculated to match LS-series engine specifications, particularly for 6.2L displacement blocks. Multi-layer steel construction provides superior gasket strength and conformability compared to conventional designs, ensuring consistent sealing performance across multiple heat cycles and high boost conditions. The .052-inch thickness is optimized to maintain proper combustion chamber volume and compression ratio while accommodating machined cylinder head surfaces typical of race-prepped LS engines.

This gasket is ideal for builders and racers constructing or rebuilding LS-series engines for drag racing, road racing, street performance, and engine dyno testing. Right-hand designation ensures proper fitment on the passenger side of the engine block. Professional engine builders and experienced DIY enthusiasts working on LS-platform vehicles—particularly those running turbo, supercharger, or high-compression naturally aspirated configurations—rely on Cometic's precision gasket specifications to eliminate head gasket failures that compromise both engine integrity and race day reliability.
