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.
Here's just what you need to secure a bellhousing in place. The studs are designed with a radiused head to position the bellhousing and accept nuts without the fear of cross-threading.

As the crankshaft flexes and twists, the balancer absorbs incredible amounts of kinetic energy. To ensure that the balancer is locked in place, ARP has developed these ultra-strong 200,000 psi bolts that let you exert maximum clamping force. Special features include 1/4' thick, wide area washer and an extra tall 12-point head that accepts a deep socket and eliminates the worry of stripping the head.
