ARP's Harmonic Damper Bolt Kit is optimized for increased strength and reliability. As the crankshaft bends and twists, these bolts are required to absorb incredible amounts of energy. These bolts are engineered to lock the Balancer in place. These bolts are rated at 200,000 PSI tensile strength. ARP's Bolts maintain molecular integrity due to being cold forged and then heat treated in order to exceed the stock fasteners in strength and longevity.
