Description

Gerzy Bear Performance is proud to offer custom ATI Harmonic Crankshaft Super Damper Pulley assemblies for all J-Series engines based on the engine code grouping selected in the drop-down menu.

Designed and tuned to eliminate crankshaft harmonics that cause parasitic HP loss, ATI Harmonic Crank Super Dampers make use of a durable non-bonded elastomer to absorb torsional and resonant vibrations. The triple band elastomer core in all of our J-series ATI based dampers are rated up to 800hp for Street, NHRA and IHRA racing usage. If more horsepower is made, then the time between replacement of the elastomer bands simply decreases from normal 10 years service interval based on ATI's official recommendations. For more information regarding the benefits of a Harmonic Crank DAMPER (not BALANCER; as all J-Series engines are internally factory balanced through piston, rod, and crankshaft bob weight ratios) please read the following article from Engine Builder Magazine at https://www.enginebuildermag.com/2019/06/harmonic-balancers-and-dampers.
