Reducing torsional vibration is pivotal to preventing overwhelming resonance and eventually crankshaft failure. As the crankshaft flexes and twists, the harmonic balancer absorbs incredible amounts of kinetic energy. This high quality and sturdy ARP Harmonic Balancer Bolt Kit helps to maintain the integrity and firmness of the harmonic balancer, or crankshaft damper, in your small block or big block engine.
