Get rid of damaging harmonic vibrations.
These Super Damper standard
harmonic balancers from ATI Performance Products are specifically designed for
high-rpm engines. Their proven elastomer is designed and tuned to eliminate
harmful crankshaft harmonics that cause parasitic horsepower loss. They are
actually two dampers in one--a 4 in. diameter inner damper and a 6 3/8 in., 7

These dampers are engineered to all but eliminate worn parts and timing
problems. They're tunable in the field, rebuildable, and extremely efficient at
