ATI has designed a 6.325” damper for the Mistubishi Evolution VIII & IX 4G63 for high horsepower street & race use. This new design is a direct replacement for the stock OEM damper. The heart of this unit is the tried and true "damper within a damper” design that has put ATI ahead of the rest. The outer shell is machined to utilize the factory serpentine belt set-up and mounts to the factory crank via a custom hub which replaces the stock timing gear. The damper's outer diameter is 12% larger than OEM. The factory lower timing cover will need to be trimmed for hub clearance.

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

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.
