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.
