Vulcan CR Head Gasket LSX LH 4.200 x .039

The Vulcan CR Head Gasket LSX LH 4.200 x .039 from SCE Gaskets is designed for serious LSX engine builders and high-performance mechanics who demand reliability under extreme conditions. This gasket is specifically engineered for the left bank of LSX applications, making it ideal for custom builds, forced induction setups, and high-output naturally aspirated engines.

With a bore diameter of 4.200 inches and a thickness of .039 inches, this gasket is precisely calibrated for LSX block geometry. The SCE Vulcan CR composite material is designed to resist blowby and maintain gasket crush under peak firing pressures, ensuring durability during thermal cycling typical of turbocharged and supercharged applications.

Engine builders and mechanics working on LSX platform modifications—from street performance to full competition duty—can rely on this gasket for its controlled crush rating, which prevents over-torquing damage while maintaining a reliable seal across repeated heat cycles and pressure spikes.
