The importance of pressure plate bolts in a racing or hi-performance street application cannot be emphasized nearly enough. These fasteners play a key role in both the performance and safety of a vehicle. Because of this, ARP has developed special pressure plate bolts that are application specific to ensure the optimum grip length. These Pro Series bolts, originally developed for NASCAR Winston Cup competition, are made from a premium grade chrome moly and hardened to a nominal tensile strength of 200,000 psi. The bolts feature a large diameter, low-profile design, and the kits come complete with washers.
