ATI Super Damper harmonic balancer shells are specifically designed for high-rpm engines. Their proven elastomer is designed and tuned to eliminate harmful crankshaft harmonics that cause parasitic horsepower loss. These damper shells are engineered to all but eliminate worn parts and timing problems. These are the shells only and must be used with an ATI hub, which is sold separately.
