Super Damper® Harmonic Dampers

The patented ATI Super Damper is the only crankshaft damper designed exclusively for high performance Chrysler, Dodge and Mopar Engines - including the new HEMI! 
Whether you race or just drive on the street, ATI's harmonic balancers are the perfect choice.

  • Eliminates torsional crankshaft vibrations
  • Exceeds SFI 18.1 specs
  • Black zinc chromate finished
  • OEM equipment on 392 Mopar Crate Engines
  • Tunable, rebuildable, and extremely efficient at ALL RPM
  • Laser engraved 360° timing marks
  • Adds ~3 PSI of boost

Inner and outer shells are available in aluminum or steel, and contain a steel inertia weight. This inertia weight has six (2-ring design) or eight (3-ring design) computer machined grooves to retain the proper durometer O-rings (dyno tested for each application).

The PCM calibration for the vehicle must be revised to accommodate the increased boost level.
