SBC LS1/LS6 Head Bolt Kit

The SBC LS1/LS6 Head Bolt Kit from ARP is essential for building reliable, high-performance engines for small-block Chevy and LS-series platforms. This kit is designed for both stock replacement engines and those pushing over 500 horsepower in modified street or race applications.

Manufactured from premium alloy steel, ARP's head bolts provide superior clamp load and predictable stretch characteristics under thermal cycling. This ensures that the cylinder head clamping force and block integrity are maintained, especially under extreme conditions such as sustained boost or nitrous applications.

Ideal for serious LS engine upgrades, this head bolt kit is compatible with truck and muscle car applications as well as dedicated race engines. Proper installation requires a torque wrench and a detailed service manual for your specific engine family, ensuring optimal performance and longevity.
