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.
Whether you're running high boost, heavy towing, or aggressive tuning, the Gator Fasteners HSK66 kit is built to handle extreme conditions. Unlike factory head bolts that stretch and fail under high pressure, these heavy-duty head studs ensure maximum reliability for drag racing, sled pulling, off-road performance, and daily driving.
Upgrade to Gator Fasteners Heavy Duty Head Studs and experience the difference in strength, reliability, and performance—because "Nothing Bites Like Gator".
