ATI has designed a 6.325” damper for the Mistubishi Evolution VIII & IX 4G63 for high horsepower street & track use. This new design is a direct replacement for the stock OEM dampe r. 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.
