The Mitsubishi 4G63 is legendary for its high-revving capabilities, but it is also prone to crankshaft vibration issues at high power levels. The ATI 6.78-inch Aluminum Super Damper (918250) is specifically designed for the Evo 8 to mitigate these harmonics. This unit features an integral lower cam drive, making it a critical upgrade for engines running high-lift cams or aftermarket timing setups.
By replacing the factory damper with the ATI Super Damper, you reduce the risk of crankshaft failure and extend the life of your engine bearings. The lightweight aluminum construction also improves engine response, allowing the 4G63 to rev faster and more smoothly. This is a must-have component for any Evo owner pushing beyond stock horsepower levels. The precision engineering ensures that you get a perfect balance every time, even under the most demanding racing conditions. Trust GGCRACING to deliver the performance parts your Mitsubishi needs to dominate the track.
