DAMPER 6.78 AL 6 GRV 3RG 2011+ HEMI 5.7 CHALLENGER CHARGER 300 DURANGO GRA

The patented ATI Super Damper is the only crankshaft damper designed exclusively for high performance Chrysler, Dodge and Mopar Engines - including the new HEMI! Whether you race or just drive on the street, ATI's harmonic balancers are the perfect choice. It eliminates torsional crankshaft vibrations and exceeds SFI 18.1 specs. The damper features a black zinc chromate finish and laser engraved 360° timing marks. It is tunable, rebuildable, and extremely efficient at all RPM. Inner and outer shells are available in aluminum or steel, and contain a steel inertia weight. This inertia weight has six (2-ring design) or eight (3-ring design) computer machined grooves to retain the proper durometer O-rings (dyno tested for each application). This part is OEM equipment on 392 Mopar Crate Engines.
