Product Description

The ATI 918471 Super Damper is engineered specifically for Honda and Acura vehicles equipped with B-series engines. With a 7.074" outer diameter and approximately 7.40 lb weight, this damper replaces the OEM harmonic balancer to better control crankshaft torsional harmonics, reduce vibration and improve engine longevity -- particularly in high-RPM or high-power builds.
