All Pro Series bolts are cold forged to ensure molecular integrity, heat treated prior to thread rolling and machining, and are rated at 200,000 PSI tensile strength. ARP Pro Series head bolt kits are application specific, designed for use with typically competition only components. These fasteners deliver superior strength and meet the ARP zero defect zero failure quality standard. Hardened and parallel ground washers are included with each kit to ensure even load distribution and accurate torque readings. All Pro Series head bolts have a reduced wrenching hex or 12 point head and wide area flange to eliminate the need for valve train removal for cylinder head retorquing and permits the use of larger diameter valve springs. Most applications have undercut short bolts that can help eliminate head gasket failures through providing more stretch to compensate for the additional compression of gaskets.

ARP only uses premium grade 8740 alloy and a proprietary ARP2000 alloy that are rated for superior to “aircraft” quality alloy steels. Secondly, each stud is placed vertically into special racks and precisely heat-treated to 200,000 psi for the 8740 material and 220,000 psi for the ARP2000 material. This procedure ensures complete heat penetration and the results are far superior to those lesser quality studs from other manufacturers who just dump pieces in a basket and hope for the best.
