ATI Super Damper Harmonic Damper | 1G / 2G DSM & Evo 8/9

Mitsubishi Super DamperHarmonic Damper

ATI has designed a 6.325 damper — Part # 918250 — for the Mistubishi Evolution VIII & IX 4G63 for high horsepower street &track 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.
