When it comes to pushing the limits of your LS Gen III engine, the Gator Fasteners Heavy Duty Head Stud Kit (HSKLS3) is built to handle extreme power and high boost applications. Designed for Chevy/GMC LS1 & LS6 engines (2004-20), these heavy-duty head studs ensure maximum clamping force, superior strength, and long-term durability-eliminating head lift even in the most demanding conditions.

Engineered for Maximum Strength
Manufactured from HD220, Gator's proprietary high-strength material, these head studs far exceed the capabilities of other brands that are using standard 8740. The Gator Fasteners HSKLS3 kit is specifically designed to outperform the competition, providing a higher tensile strength and improved fatigue resistance for boosted and high-compression LS applications.

Trust in Gator Fasteners because Nothing Bites Like Gator.
