Super Damper Harmonic Balancer

The ATI 918487 Super Damper is a patented crankshaft damper engineered exclusively for high-performance Chrysler, Dodge, and Mopar engines, including the Gen III Hemi 5.7L and 6.4L variants. It meets and exceeds SFI 18.1 specifications, ensuring its suitability for racing applications. The damper features a durable black zinc chromate finish and precisely laser-engraved 360° timing marks for accurate engine tuning. Constructed with a combination of aluminum or steel outer shells and a steel inertia weight, the Super Damper utilizes a dual-ring (6-groove) or triple-ring (8-groove) design. These grooves securely retain the proper durometer O-rings, which have been dyno-tested for each specific application to ensure optimal performance and reliability. This model includes a 15% underdrive pulley and is compatible with VVT-equipped engines. It is an ideal choice for both street-driven performance vehicles and dedicated race cars seeking superior harmonic control and vibration reduction.
