Blown or weeping head gasket on your Duramax? This Sinister Diesel Black Diamond gasket is a direct replacement for the driver side head on 2001-2010 LB7, LLY, LBZ and LMM engines. It's a 5-layer stainless steel MLS gasket with an FKM coating on the sealing surfaces, built to seal tight and stay sealed.

This is the Grade C gasket, the thickest of the three Duramax grades at 1.05mm. Duramax head gaskets are graded by piston protrusion, so match the grade on the gasket you're pulling off (or measure protrusion if the block or heads have been machined) before you order.
