ARP uses premium grade 8740 alloy that is heat treated to 200,000 p.s.i. 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. Following heat treat, each stud is centerless ground to make it as close to perfectly concentric as possible. This procedure involves about ten very slight cuts and results in an exceptionally straight part. ARP studs are thread rolled after heat treat which gives them about 1000% better fatigue strength than studs that are threaded prior to heat treat (a very common industry practice). It costs more to do it this way because it's tough on tooling but the results are well worth the extra effort.
ARP main studs eliminate main cap walk and fretting as well as protecting the threads in your engine block. All kits come complete with hardened parallel-ground washers and high quality nuts. Manufactured from 8740 chromoly steel, heat-treated in house to 200,000 p.s.i. tensile strength and precision J-form threads rolled after heat treat to create a fastener that has threads 1000% stronger than OEM produced studs. A must for high horsepower, high rpm engine applications.
