ATI Super Harmonic Street Damper - Toyota 2ZZ-GE Celica

ATI Super Harmonic Street Damper - Toyota 2ZZ-GE Celica

Factory dampers and non-dampened pulleys offer no protection to high performance engines. These ATI sport compact Super Dampers provide the balanced dampening of torsional crankshaft vibrations at all rpm levels. The street versions have both OEM serpentine groove locations and are very close to OEM size. The smooth-shell race version dampers are designed for high performance race use. Both dampers come with laser-etched timing and exceed SFI 18.1 Safety Certification standards for competition use.

The patented ATI Super Damper is the only damper designed exclusively for high performance engines.


  • Eliminates torsional crankshaft vibrations
  • Exceeds SFI 18.1 specs
  • Laser engraved 360° timing marks
  • Black zinc chromate finished
  • 3-ring design
  • 5.670" outside diameter
  • 3.60lbs weight
  • For use on 2ZZ-GE engines

Installation Note: ATI dampers are a 1-thousandths press fit, they do not just slide on like OEM crank pulley. They will need to be pressed onto the crank snout with a damper install kit.
