As the crankshaft flexes and twists, the balancer absorbs incredible amounts of kinetic energy. To ensure that the balancer is locked in position, ARP has developed these ultra-strong 200,000 psi bolts that let you exert maximum clamping force. Special features include ¼” thick, wide area washer and an extra tall 12-point head that accepts a deep socket and eliminates the worry of stripping the head. 16mm x 2.0 thread, 12 point head. It Fits LS7 and LS9 engines.
