ARP Diesel Head Stud Kits
Premium grade 8740 alloy that is rated far superior to "aircraft" quality. Then, each stud is precisely heat-treated to 220,000psi. ARP studs are thread rolled after heat-treat, which gives them about 2000% (that's 20 times) better fatigue strength than those studs that are threaded prior to heat-treat (a very common industry practice). All kits come complete with hardened parallel-ground washers and high quality nuts.
