Mitsubishi Super Dampers
The patented ATI Super Damper is the only damper designed exclusively for high performance engines.
4G63 Evolution 8 & 9 Super Dampers ATI has designed a 6.325” damper -- Part # 918250 -- 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.    4G63 & 4G64 DSM (Eclipse, Eagle Talon, Plymouth Laser) 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.
