Mopar Big Block Super Damper Harmonic Balancer by ATI Performance

Patented ATI Super Damper standard harmonic balancers are the only crankshaft dampers designed exclusively for high-performance engines. Inner and outer shells are available in aluminum or steel and contain a steel inertia weight. The inertia weights have six (2-ring design) or eight (3-ring design) computer-machined grooves to retain the proper durometer O-rings (dyno tested for each application). Whether you race or just drive on the street, ATI harmonic balancers are a perfect choice.
