GM LSX MLX Head Gasket LH 4.100 .040

The GM LSX MLX Head Gasket LH 4.100 .040 is engineered to meet the rigorous demands of high-performance GM LS-series engines. This left-hand side cylinder head gasket is ideal for enthusiasts and professional builders who require precision specifications for their engine builds.

Utilizing Cometic's Multi-Layer Xtreme (MLX) technology, this gasket features a multi-layer steel construction designed to withstand the increased cylinder pressures often found in modified LSX platforms. With a 4.100-inch bore and a 0.040-inch compression thickness, it allows for fine-tuning of the engine's quench height and compression ratio, optimizing combustion efficiency and preventing detonation in high-output environments.

This gasket is sold individually and is compatible with a wide range of GM LS-series blocks. It is a staple for those conducting a top-end refresh or a complete engine overhaul where exacting tolerances are required. Ensure that your build's specific bore and deck clearance requirements align with this 4.100-inch bore option for the best fit.
