ARP head stud kit Ford Sierra Rs Cosworth

Complete ARP head stud kit for all Ford Sierra Rs Cosworth and Escort Cosworth.

ARP uses a premium grade 8740 alloy that is rated far superior to aircraft quality. Each stud is placed vertically in special racks and precisely heat-treated to 190,000 psi. 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. ARP studs are thread rolled after heat treatment, which gives them about 2000% (that's twenty times) better fatigue strength compared with studs that are threaded prior to heat-treat (a very common industry practice)
