ATI Damper Mitsubishi Evo X 4B11

Built for the Mitsubishi Evo X, this ATI 5.67" Super Damper (6-groove, aluminum, 1-piece) offers a 3% underdrive setup for improved engine efficiency and reduced parasitic drag. Designed to handle high RPMs and street-driven abuse, it reduces harmonic vibration to extend engine life and keep your build running smoother under load.

Made from lightweight aluminum, this 1-piece damper provides OE fitment with no spacers required. The 6-rib pulley configuration supports factory belt systems, while the underdrive design frees up horsepower without compromising drivability. Ideal for Evo 10 owners who want more performance and reliability from their daily or weekend build.
