ARP1352501 - ARP Balancer Bolt- Big Block Chevy- 5/8" Head- 1/2"-20 Thread- 12 Point Head With Washer

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.
