ARP - Head Studs. Obtaining the optimum cylinder head-to-block sealing is especially critical in small displacement engines employing high compression pistons or power adders like turbochargers, nitrous oxide and superchargers. That's why ARP head studs are popular among leading Sport Compact/Import racers. ARP - Rod Bolts. The "weak link" in a connecting rod has always been the bolt, and racers know that nobody builds a better bolt than ARP. ARP in-house forges using only the finest quality materials, then heat-treats using special vertical racks to ensure complete 360 degree penetration. Threads are then rolled after heat-treat to provide 10 times more fatigue strength. ARP - Flywheel Bolts. Flywheel and Flexplate bolts play an important role in the performance and safety of race cars and street machines alike. That’s why the fastener experts at ARP have developed special bolts that are far superior to OEM hardware. ARP - Pressure Plate Bolts. 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. ========================================================================================= We also accept orders over the phone...................
