Swap out any leaking or blown head gasket in your Duramax engine using this Sinister Diesel Duramax head gasket. It works as a direct replacement for OE head gaskets in 2001 to 2010 GM Duramax LB7, LLY, LBZ, and LMM turbo diesel engines, so you don’t need to worry about proper fitment.

Each Sinister Diesel Black Diamond Head Gasket has been designed specifically for the extreme heat and high compression of your Duramax turbo diesel engine. The 5 layers of stainless steel plus an adaptive fluoroelastomer (FKM) coating combine to create a heavy-duty seal for each of the cylinders. Sold individually, you need to select either a driver or passenger side gasket.


  • Construction - Multi-layer Steel
  • Product Design - Passenger Side, Grade C 1.05mm thickness, Coated with Adaptive fluoroelastomer (FKM)
  • Kit Includes - (1) Sinister Diesel Black Diamond 20mm Head Gasket
