ARP HARMONIC BALANCER BOLT KIT 235-2502 BB CHEVROLET 1-1/16 SOCKET SIZE, 1/2-20 THREAD SIZE, 1.550 UHL

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.
