As the crankshaft flexes and twists, the harmonic balancer or damper absorbs incredible amounts of kinetic energy. To ensure that the balancer is locked in position, ARP has developed an ultra strong 190,000 psi bolt 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.

In 1968 racing enthusiast Gary Holzapfel saw many of his friends’ broken engines were caused by fastener failure. At the time no commercially available studs and bolts up to the challenge. So Holzapfel called upon his many years of fastener making experience for a leading aero-space subcontractor and formed ARP (Automotive Racing Products) in California (USA).

Today ARP are know as the best high performance fastener manufacturer in the world, you will find their product in many leading race teams in Formula 1, IndyCar, NASCAR and NHRA Drag Racing. Affordable Aerospace technology and quality that is out of this world, make ARP your first choice for your high performance streeter or race car.
