Spartan MLS Head Gasket GM LH 4.201 x .051

The Spartan MLS Head Gasket GM LH 4.201 x .051 is a precision-engineered cylinder head gasket designed specifically for General Motors LS-series engines. This multi-layer steel gasket is engineered to seal the critical interface between the cylinder head and engine block, preventing coolant and oil leakage while maintaining combustion chamber integrity. Built for drivers and engine builders who demand reliable sealing performance in high-performance and stock LS applications, this left-hand gasket is an essential component for engine rebuilds, repairs, and performance upgrades.

Manufactured by SCE Gaskets, the Spartan MLS head gasket utilizes multi-layer steel construction to deliver superior durability and sealing capability across a wide temperature and pressure range. The 4.201-inch bore diameter is precisely sized for LS-series cylinder heads, while the 0.051-inch compression thickness ensures proper combustion chamber volume and engine tuning compatibility. Multi-layer steel gaskets excel at conforming to irregular machining surfaces, reducing blow-by and preventing gasket failure even under elevated boost conditions or extreme temperature cycling. This driver-side configuration is specifically engineered to match OEM specifications and performance requirements of GM LS engines.

Whether you're rebuilding a stock LS engine, upgrading a performance application, or repairing a damaged gasket surface, the Spartan MLS Head Gasket GM LH 4.201 x .051 delivers proven sealing performance for a fraction of OEM pricing. LS engine enthusiasts, professional mechanics, and engine shops rely on this gasket for street cars, track builds, and marine applications. Installation requires standard head gasket procedures: proper surface preparation, correct torque specifications, and following GM LS-series service bulletins. This single gasket is the left-hand unit; be sure to order the corresponding right-hand gasket and additional components needed for a complete head gasket set.
