ATI Performance Products ATI917118 Super Damper Harmonic Balancer

The ATI Performance Products ATI917118 Super Damper is a high-performance torsional damper (harmonic balancer) engineered to reduce crankshaft torsional vibration, protect engine internals, and improve overall power output. ATI Super Dampers are trusted by professional racing teams and performance enthusiasts across drag racing, road racing, circle track, and street/strip applications.

The damper is SFI 18.1 certified, meeting sanctioning body requirements for competition use.
