4G63 Evolution 8 & 9 Super Dampers


PRICE: $470

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.
