LS1 Head Stud Kit 12pt.

The ARP LS1 Head Stud Kit 12pt is the fastening solution serious LS engine builders and performance mechanics rely on when maximum reliability is non-negotiable. This complete kit includes 8 studs and 8 nuts, making it ideal for those looking to enhance the performance and durability of LS1, LS2, and LS-Series engines.

Unlike standard bolts, studs eliminate the twisting stress that occurs during installation and provide superior clamp load consistency across all eight cylinder head locations. ARP's chromoly construction delivers tensile strength that holds preload under extreme combustion pressure, thermal cycling, and vibration without relaxation over thousands of miles. The 12-point design distributes load over a larger contact surface, reducing the risk of stripping and allowing for more precise torque specifications.

This kit is essential for anyone building a performance LS engine, whether you're running 8 pounds of boost or a naturally aspirated 8,000 RPM build. Each stud is individually manufactured and quality-tested to ARP's exacting standards, ensuring repeatable clamping force that keeps your head gasket sealed tight. Upgrade your engine's reliability and performance with the ARP LS1 Head Stud Kit.
