ATI Performance Products ATI918887 Super Damper Harmonic Balancer Ford Powerstroke Diesel - 6.4L

The ATI Performance Products Super Damper (Part # 918887) is a high-performance harmonic balancer engineered for the Ford 6.4L Powerstroke diesel engine. Designed for both street and performance applications, this damper provides superior crankshaft harmonic control compared to the factory unit, helping protect your engine's rotating assembly from damaging torsional vibrations.
