ARP (Automotive Racing Products) makes the strongest fasteners in motorsport — head studs, main studs, rod bolts, and flexplate bolts used by every Formula 1, NHRA, NASCAR, and championship motorsport program. Aerospace-grade alloys, exact-fit machining.
Ensure your engine's integrity under extreme pressure with the ARP Pro-Series 12pt Head Stud Kit. Specifically engineered for 1997-2003 Chevy LS1 engines, this kit provides the superior clamping force required for high-performance builds. Whether you are running a stock block or a modified setup, these studs prevent head gasket failure and ensure consistent torque distribution across the cylinder head.
Each kit includes high-quality heat-treated studs, precision-machined nuts, and hardened parallel washers to ensure accurate torque readings. By replacing factory bolts with these high-strength studs, you eliminate the risk of thread stripping and gasket blowout common in high-compression or forced-induction applications. The 12pt nut design allows for easier access in tight engine bays, making installation more efficient for professional builders and enthusiasts alike. Trust in the industry-leading quality of ARP to keep your engine sealed tight. For all your high-performance engine hardware needs, rely on the experts at GGCRACING.
