LS1 Head Stud Kit 6pt.

The ARP LS1 Head Stud Kit 6pt. is a premium fastening solution designed for GM LS-series engine builders and enthusiasts who require maximum cylinder head clamping force and reliability. This kit replaces factory bolts with head studs to provide superior load distribution, reduce bolt stretch, and maintain consistent clamp load across repeated heat cycles, making it essential for high-performance applications.

Constructed from aerospace-grade chromoly steel and finished in black oxide, the LS1 Head Stud Kit 6pt. features hardened studs with matching hex nuts that ensure uniform torque application and thread protection. The six-point nut design spreads load more evenly than four-point alternatives, which helps to reduce the risk of fastener galling and thread damage during installation or future removal. ARP's precision manufacturing tolerances guarantee a correct fitment on all LS-series cylinder heads.

Whether you're rebuilding an LS1, LS2, LS3, or another variant in the LS family, this head stud kit provides the security and consistency that premium head studs offer. Proper installation requires adherence to ARP's recommended torque specifications, ensuring optimal performance for both street and competition LS builds.
