4.150 MLX Head Gasket .052 GM LSX Race LH

The 4.150 MLX Head Gasket .052 GM LSX Race Left-Hand is a precision multi-layer steel cylinder head gasket engineered for high-performance GM LS-series engine builds, particularly suited to 6.2L applications and racing configurations. This gasket is designed for serious LS engine builders and race teams developing high-displacement or boosted powerplants that demand consistent sealing under sustained peak loads.

With a 4.150-inch bore diameter and 0.052-inch compression thickness, this gasket delivers the critical sealing performance required in forced-induction and naturally aspirated race engines. The multi-layer steel construction provides superior gasket durability compared to conventional composite designs, withstanding the extreme cylinder pressures generated in turbocharged, supercharged, and high-rev naturally aspirated LS builds.

This left-hand configuration ensures proper fitment for driver-side cylinder head installation on V8 applications where port orientation and firing order require directional gasket placement. Whether building a street-performance 6.2L LS3 or a competition engine, this gasket is essential for achieving the target compression ratio and chamber volume in modified LS-series heads.
