Gator Fasteners Heavy Duty Head Stud Kit – 2004-2020 Chevy/GMC LS Gen III Engines (HSKLS3)

Keep your LS-powered GM truck's head gaskets sealed under boost, nitrous, or a bigger cam with the Gator Fasteners Heavy Duty Head Stud Kit for 2004-2020 Chevrolet and GMC trucks and SUVs with a Gen III LS engine. Factory torque-to-yield head bolts stretch and lose clamping force once you move past stock power levels — this kit replaces them with reusable, precision-machined studs for consistent, repeatable clamping load every time the heads are serviced. A common first step for any OBS/GMT400 truck getting an LS swap.

• Made from HD220 high-strength material rated to 220,000 PSI tensile strength
• Rolled threads after heat treating for maximum fatigue strength and thread integrity
• Precision machined and heat treated for consistent torque values
• Complete kit includes studs, washers, and nuts for both cylinder heads
• Includes Gator Juice assembly lubricant for accurate torque readings on install
• Fits: 2004-2020 Chevrolet/GMC trucks and SUVs with a 4.8L, 5.3L, 5.7L, 6.0L, 6.2L, or 7.0L Gen III LS engine (LS1/LS6), including popular LS-swap builds

Mfg Part #: HSKLS3. A smart upgrade any time the heads come off an LS build for boost, nitrous, a cam swap, or a performance tune.
