ATI Race Balancer 1000HP - Mitsubishi 4B11SKU: ATI-918254
The patented ATI Super Damper is the only damper designed exclusively for high performance engines.
Designed for up to 1000HP and high RPM applications, the ATI Super Damper is the best available on the market.
ATI has designed a 6.325” damper for the Mistubishi Evolution 4-9 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.
