Шкив с дампером предотвращает продольные вибрации коленвала. 

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 timing marks
- Black zinc chromate finish

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.

Part number: 918250
