There are many important reasons to use ARP main stud kits, including the elimination of main bearing cap walk and fretting, as well as protecting the engine block threads. All kits come complete with parallel-ground hardened washers and high-quality nuts. Some applications feature oil deflector mounts and specially designed spacer studs with serrated lock nuts to position the deflector and securely fasten it. The studs are made from 8740 chrome-moly steel, internally heat-treated to achieve a tensile strength of 190,000 psi, and 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. First, more accurate torque readings are obtained since studs do not twist into the block. All clamping forces are applied on a single axis. Additionally, less stress is placed on the block threads, which contributes to a longer block life (critical in aluminum blocks). Finally, engine assembly is made easier, and proper cap alignment is ensured every time.
