The ARP High Performance Main Bolt Kits are forged from premium 8740 chrome moly and all the bolts feature and generous under-head radius and heat treating for utmost reliability. The threads are rolled after heat treating, which makes them about 1000% stronger than most other main bolts. These bolts are nominally rated at 180,000 psi, and are a premium replacement for any OEM fastener.

There are many important reasons to use ARP main stud kits, including the elimination of main cap walk and fretting, as well as protecting the threads in your engine block.
