The importance of pressure plate bolts in a racing or high 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 optimum grip length. These ARP Pro series bolts, originally developed for NASCAR Winston Cup competition, are stronger and are rated at 200,000 psi. They feature a large-diameter, low-profile design and come complete with washers.
