ARP Harmonic Balancer Bolt Kit GM LS Engines (except LS7) – 234-2503

�
Harmonic balancer bolts resist the flexing and twisting of the balancer as it absorbs large amounts of kinetic energy. ARP has developed these bolts to ensure that the balancer remains locked in position. They yare rated at 200,000 psi tensile strength so you can exert the maximum clamping force.The special features of ARP’s 234-2503 include a quarter inch thick, wide area washer and an extra tall 12-point head that will accept a deep socket with no worries about stripping the head.
