Super Damper® Harmonic Dampers

The patented ATI Super Damper is engineered exclusively for high performance engines, offering superior control of torsional crankshaft vibrations. Exceeding SFI 18.1 specifications, each damper features a durable black zinc chromate finish and laser-engraved 360° timing marks for precise setup. The design is tunable, rebuildable, and maintains high efficiency across all RPM ranges.

Constructed with inner and outer shells available in either aluminum or steel, each damper incorporates a steel inertia weight. The inertia weight features six (2-ring design) or eight (3-ring design) computer-machined grooves to retain the correct durometer O-rings, which are dyno tested for each specific application.
