ARP Header Bolt Kits, Drilled, NASCAR Compliant

ARP offers special NASCAR header bolts that have been drilled for use of safety wire. They are made from heat-treated 8740 chrome moly steel (with a black oxide finish - rated at 180,000 psi) or Stainless 300 that is polished to a bright shine (nominally rated at 170,000 psi tensile strength

ARP NASCAR Compliant Drilled Header Bolt Kits are considerably stronger than Grade 8 hardware), and engineered to provide complete reliability in the most severe racing environments. They are available in hex or 12-point heads. Through use of safety wire, exhaust headers will maintain original tightness and can’t back off!
