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.
