2001-2016 Duramax Wave-Stopper Grade C Driver Side Head Gasket (54585)

Fits

Ensure a professional-grade seal on your engine overhaul with the Mahle Original® Wave-Stopper Cylinder Head Gasket. Engineered for the 2001–2016 Duramax 6.6L, this Grade C (1.05mm thickness) gasket utilizes advanced Multi-Layered Steel (MLS) construction and "Combustion Load Limiter" technology. This specialized design allows the gasket to dynamically acclimate to the extreme thermal loads and cylinder pressures found in high-output diesel engines. As a premium direct-fit replacement, it provides a durable, leak-free seal for standard bore cylinders on the left-hand (driver) side of your engine block.
