There are many important reasons to use ARP main stud kits, including eliminating main bearing cap walk and fretting, as well as protecting the block threads. All kits include parallel-ground hardened washers and high-quality nuts. Some applications feature oil deflector mounts and specially designed spacer studs with serrated locknuts to position the deflector and secure it. The studs are manufactured from 8740 chromoly steel, heat-treated in-house to 190,000 psi tensile strength, with precision J-form threads rolled after heat treatment to create a fastener with threads 2000% stronger than others. ARP recommends using main studs instead of bolts whenever possible for several key reasons. Firstly, they allow for more accurate torque readings, as the studs do not twist within the block. All clamping forces are applied along a single axis. Also, less stress is placed on the block threads, which contributes to a longer block life (critical for aluminum blocks). Finally, they facilitate engine assembly and ensure correct cap alignment every time.
