Quick Ship SKU #: ATI-917365C ATI 917365C Super Damper Harmonic Balancer Race Version 89-91 and 98.5-02 Cummins

Designed with absolute precision in mind, the ATI Super Dampers are without a doubt the highest quality harmonic balancers built for diesel engines of all builds. But if you're building a full competition built engine that does NOT include a pulley because you're doing away with your belt-driven pump, A/C, alternator, etc., then the Super Damper RACE VERSION is what you're looking for. By eliminating torsional vibration at the crankcase, your truck will come alive faster and run smoother.

Built out of steel in the good old USA and black zinc chromate finished with laser etched timing marks, these dampers EXCEED SFI 18.1 specs.
