ARP Early LSx Head Bolts

Description

These ARP High Performance series head bolt kits are tough! They are rated at 170,000 psi–15 percent stronger than Grade 8 fasteners. They come available with hex heads or reduced wrenching 12-point heads that eliminate the need for valvetrain removal when re-torquing cylinder heads. This head bolt kit fits LS1s and LS6’s built before mid 2004.
