Description

When it comes to keeping your 6.6L Duramax diesel engine (LB7, LLY, LBZ, LMM, LML) together under extreme stress, the Gator Fasteners Heavy Duty Head Stud Kit (HSK66) is the ultimate solution. Designed to withstand high boost, heavy towing, and extreme performance applications, this kit provides superior clamping force to eliminate head gasket failures.
