ARP uses premium grade 8740 alloy that is rated far superior to that of supposed “aircraft” quality.
All Pro Series ARP2000 studs are centerless ground, heat treated prior to thread rolling and machining, and are nominally rated at 220,000 psi. These fasteners deliver a 40% increase in tensile strength over the OEM Torque to Yield (TTY) bolts.
All bolts are precision centerless-ground and thread-rolled to Mil-S-8879 specs. Each utilizes a black oxide finish that protects them from wear and corrosion.
Obtaining the optimum cylinder head-to-block sealing is critical in small displacement engines employing high compression pistons or engines that utilize high pressure outuput from forced induction
