Replace a leaky, blown head gasket on your Duramax diesel engine with this Sinister Diesel Duramax head gasket. Thanks to a multi-layer steel construction, this gasket will withstand the extreme temperatures and pressure generated by a turbo diesel engine, so you can count on it to last for a long time. It's a direct replacement for the OE head gasket in your 2001-2010 GM Duramax Diesel LB7, LLY, LBZ, and LMM diesel engine.

A 5-layer stainless steel construction, combined with an adaptive fluoroelastomer (FKM) coating ensure a tight seal for each cylinder. That means fluids and gases both will be kept in their proper places, leading to smooth engine operation. Each head gasket is sold individually, so select either a passenger or driver side gasket for your truck.


  • Construction - Multi-layer Steel
  • Product Design - Passenger Side, Grade B 1.00mm thickness, Coated with Adaptive fluoroelastomer (FKM)
  • Kit Includes - (1) Sinister Diesel Black Diamond 20mm Head Gasket
