ATI Super Damper, SFI approved for street and race applications. Built specifically for high-performance applications, the ATI Super Damper provides balanced dampening of torsional crankshaft vibrations at all RPM while overdriving the supercharger to increase supercharger boost levels when combined with custom tuning that is needed to disable the factory overboost controls.
The patented ATI Super Damper is the only damper designed exclusively for high performance engines.
- Eliminates torsional crankshaft vibrations
- Exceeds SFI 18.1 specs
- Laser engraved 360 timing marks
- Black zinc chromate finished
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 degree timing marks.
We've made the kit easy for you or your installer. Per Chrysler, this damper requires replacement of the factory crank bolt (Part #6510536AA) and uses a torque rating of 239 ft-lbs. With this pulley, you can select the crank bolt, the correct longer 10-Rib blower belt, our recommended Crank Pin kit and even our custom tuning package where we will ship you a new replacement PCM, a Diablosport Trinity Handheld tuner and we will email tune your car for you!
Expert Installation at HHP: You can also have this pulley installed and dyno tuned with Diablosport CMR Software on a replacement PCM with all of the required parts at our Smyrna, DE location.
