IN STOCK AND READY TO SHIP! 

As the crankshaft in your 6.6L Duramax flexes and twists, the harmonic balancer is absorbing incredible amounts of kinetic energy. To ensure that the crankshaft balancer is locked in position, ARP has developed these ultra-high-strength 200,000 psi crankshaft bolts that let you exert the maximum clamping force between the damper and the crankshaft. The ARP Harmonic Balancer Bolt Kits ensure your vibration damper is properly registered to the crankshaft of the engine.

• The Duramax Damper Bolt is a 1/4"  thick stud
