ARP Heavy Duty Harmonic Balancer Bolts
As the crankshaft flexes and twists, the balancer absorbs incredible amounts of kinetic energy. To ensure that the balancer is locked into position, ARP® has developed these ultra strong 200,000 p.s.i. 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. The extra tall head also makes valve adjustment much easier.
