If your diesel truck’s head gaskets are either blown or leaking, replace them with this high-quality Sinister Diesel Duramax head gasket. A heavy-duty stainless steel design ensures the kind of seal and durability necessary to endure high temperatures and compression generated by a turbo diesel engine.


This Sinister Diesel Black Diamond Head Gasket directly replaces the OE head gasket in 2001 to 2010 Duramax LB7, LLY, LBZ, and LMM diesel engines. Each one features a 5-layer stainless steel sandwich design, plus an adaptive fluoroelastomer (FKM) coating. That means a heavy-duty seal which prevents gasses and fluids from flowing past. Select either a driver’s or passenger’s side gasket.


  • Construction - Multi-layer Steel
  • Product Design - Passenger Side, Grade A .95mm thick, Coated with Adaptive fluoroelastomer (FKM)
  • Kit Includes - (1) Sinister Diesel Black Diamond 20mm Head Gasket
