The Cometic GM LB7/LBZ/LGH/LLY/LML/LMM Duramax .040in MLS Exhaust Manifold Gasket - C15042-040 is a precision-engineered exhaust gasket with a compressed thickness of .040".
Cometic Multi-Layer Steel (MLS) exhaust gaskets are built to withstand the extreme heat and pressure cycles of high-performance exhaust systems. Featuring Multi-Layer Steel (MLS) construction, this gasket uses multiple embossed steel layers that conform to surface irregularities and maintain a positive seal. Designed to seal flanged connections between the exhaust manifold/header and the cylinder head or down-pipe, these gaskets prevent exhaust leaks that rob power and cause drone.
