MAHLE WAVE-STOPPER CYLINDER HEAD GASKET (GRADE C) 54597 & 54598 | 2001–2016 6.6L Duramax LB7/LLY/LBZ/LMM/LML

Replace a worn or failed cylinder head gasket in your 2001–2016 GM 6.6L Duramax with the MAHLE 5459X Wave-Stopper Cylinder Head Gasket. Manufactured to OEM standards, this direct-fit replacement uses a multi-layer steel construction designed to provide dependable sealing between the cylinder head and engine block.

MAHLE's patented Wave-Stopper technology incorporates concentric waves into the spring-steel active layer surrounding each combustion chamber. This design allows the gasket to adapt to changing combustion pressures and engine loads while maintaining sealing pressure around the cylinder bores.

This gasket measures 1.05mm (0.041") thick and features a 106mm (4.17") cylinder bore diameter. It is sold individually, so verify the quantity and gasket thickness required for your engine before ordering.
