Mopar 383-440 Internally Balanced All Steel Pro Race Harmonic Balancer

Pro Race harmonic dampers are designed for a wide range of high performance applications. This "all steel" damper is a direct replacement for factory cast iron versions which may fracture or disintegrate at high RPM and are not permitted by most racing organizations.

Pro Race dampers are also ideal when using a belt-driven supercharger which places additional torque loads on the damper hub. On the Race damper, the elastomer is bonded to the steel hub and ring, which is valuable when sustained high RPM is needed, such as marine or circle track applications.

Measures 7.01" in diameter and 1.54" in thickness.
