Utilizing ARP main stud kits offers numerous essential benefits, addressing issues such as main cap walk, fretting, and thread protection within your engine block. These kits include hardened parallel-ground washers and high-quality nuts, ensuring a comprehensive solution. In certain applications, provisions are made for attaching windage trays, featuring specially designed standoff studs with serrated lock nuts. This design serves to position and securely lock the windage tray in place for optimal performance.
The main studs are crafted from 8740 chrome moly steel, undergoing in-house heat treatment to achieve a tensile strength of 200,000 psi. Furthermore, the precision J-form threads are rolled after heat treatment, resulting in fasteners with threads that are 2000% stronger than alternatives. This meticulous manufacturing process ensures the reliability and durability of ARP main stud kits.
