Mitsubishi Super Dampers

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

  • Eliminates torsional crankshaft vibrations
  • Exceeds SFI 18.1 specs
  • Black zinc chromate finished
  • Tunable, rebuildable, and extremely efficient at ALL RPM
  • Laser engraved 360° timing marks

ATI has also designed a 6.325” damper -- Part # 918251 -- for the Mistubishi Eclipse, DSM 4G63 & 4G64 for high horsepower street & race use. This new design is a direct replacement for the stock OEM damper. The outer shell is machined to utilize the factory 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.

Specifications:

  • Internal Balance Damper Assembly
  • Outer Diameter: 6.325 Inches
  • Total Weight: 3.90 Lbs
  • Inertia Weight: 2.40 Lbs
  • Shell Material: Aluminum
  • Ring: 3
