ARP 234-2503 Harmonic Balancer Bolt Kit GM LS Engines

ARP 234-2503 Harmonic Damper Bolt Kit

As the crankshaft in your V8 General Motors V8 rotates, it is forced to endure massive dynamics loads. The engine's crankshaft flexes and twists transmitting these loads to the engine's 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 Harmonic Balancer Boltsthat let you exert the maximum clamping force between the damper and the crankshaft. The use of the ARP 234-2503 Harmonic Balancer Bolt ensures the damper is registered correctly to the crankshaft and that it will stay in place throughout the entire RPM band.
