    Chevy Aluminum Dampers

    Hubs for these assemblies have a 2.280'' counterbore. A standard length crank bolt is used and the mandrel bolts to the 3 pulley mounting holes. This eliminates the 4'' - 6'' long bolt that is ineffective in retaining torque. These damper assemblies are used 100% by NASCAR Cup, Busch Grand National and most endurance engine builders. Adapter part # 085-916321 is available for existing mandrels with 1.245'' pilot.

    Manufacturer's Part Number:

    ATI's patented Super Damper is the only harmonic balancer developed exclusively for high-RPM performance engines (6000+ RPM). Its proven elastomer design is 2-in-1: a 4" diameter damper and a 7" diameter damper in two shells that bolt to the crank hub.

    Inner and outer shells are aluminum or steel to contain the steel inertia weight. The inertia weight has eight computer-machined grooves to retain the proper durometer O-rings (installed at ATI and dyno tested for each application). O-ring life has been tested in Winston Cup competition over two million cycles and in drag racing engines for 10 years (exceeds SFI 18.1 specs). Units can be rebuilt by installing new O-rings. Shells have a black zinc chromate finish with computer-controlled, laser-engraved 360° timing marks.
