06-13 LS7 ARP Harmonic Balancer Bolt (ND)

Due to crankshaft flexes and twists there is a necessity to ensure that the balancer/damper is secured for high performance applications. ARP has developed these ultra strong 200,000 psi chrome moly bolts for the purpose. They have a specially designed flange with a tall 12-point head that accepts a deep socket and eliminates the worry of stripping the bolt. Includes 1/4" thick wide area washer.
