Super Damper 6-Groove Engine Balancer, 6.325" Diameter

ATI Performance Products, Inc. is proud to introduce its renowned Super Damper for the Mitsubishi Evolution 8 & 9 and 4G63 DSM Eclipse, Talon, Laser & Galant VR-4, including the popular 2.4L 4G64. The SFI Certified ATI Super Damper provides unmatched performance and engine protection for motors that turn over 6,000 RPM and is a direct replacement for the stock OEM unit. The outer shells are machined to utilize the factory serpentine belt set-up—the Evo Damper provides a single serpentine belt drive, while the DSM/Eclipse Damper has dual serpentine drives. Both dampers mount to the factory crank via a custom steel hub which replaces the stock timing gear for improved dampening at high RPM. In addition, both dampers can accommodate a trigger wheel for more accurate crank angle readings for aftermarket engine management systems. The Evolution Dampers (Part # 918250) and DSM/Eclipse Dampers (Part # 918251) exceed SFI 18.1 Safety Certification and are approved for both the NHRA & IHRA competition, where SFI-spec crank pulleys are required for vehicles running 10.99 or faster.
Unlike unbalanced underdrive pulleys, which offer no protection to high performance engines, the tunable ATI Super Damper provides balanced dampening of torsional crankshaft vibrations. Extensive dyno and on track testing by ATI has proven the Super Damper far superior to all other damper designs and assures efficiency over stock dampers, resulting in added power and response. If you are looking for guaranteed performance and protection there is only one choice, the only tunable, rebuildable, high performance damper, the ATI Super Damper.
