The MAHLE ORIGINAL/CLEVITE MLS Head Gasket for GM LS Series engines with 4.130-inch bore and 0.051-inch compression thickness is a direct-fit replacement engineered for durability and reliable sealing in high-performance and stock applications. This multi-layer steel cylinder head gasket maintains its integrity across temperature cycles and engine load variations, making it essential for any LS-series rebuild, refresh, or performance upgrade requiring OEM-quality gasket replacement.
The 0.051-inch compression thickness is precisely calculated to deliver correct combustion chamber volume and compression ratio for LS-family engines. Multi-layer steel construction provides superior fire-ring sealing and prevents leakage under boost, high RPM operation, and thermal stress. The 4.130-inch bore specification ensures proper gasket coverage across all cylinder openings without overhang or exposure to combustion pressure. This gasket is designed to work seamlessly with factory or aftermarket LS cylinder heads and stock or performance-ported block surfaces when installed with appropriate torque specifications and surface preparation.
Buyers assembling or rebuilding LS-series engines—whether for street performance, racing, or restoration—depend on head gaskets that match OEM tolerances exactly. This MAHLE ORIGINAL part is specified for LS1, LS2, LS3, LS6, and LS9 applications, as well as truck variants including the LQ4, LQ6, and related displacement families. Single gasket sold; dual gaskets required for complete head installation on V8 engines.
