ATI Performance Products 917783 Super Damper Harmonic Balancer

The ATI Performance Products 917783 Super Damper is a high-performance harmonic balancer engineered for demanding applications. This damper is designed to control harmful crankshaft torsional vibrations that can damage engine components and rob power in high-RPM performance engines.

Key Features:

• Patented Super Damper design developed exclusively for high-performance engines operating above 6000 RPM
• Precision-machined aluminum or steel outer shell with steel inertia weight for optimal vibration dampening
• Computer-machined grooves retain proper durometer O-rings that have been dyno-tested for the application
• Laser-engraved 360-degree timing marks for precise ignition timing adjustment
• Meets or exceeds SFI 18.1 safety specification for competition use
• Black zinc chromate finish for corrosion resistance and professional appearance
• Internal balance design for broad engine compatibility

ATI Super Dampers have been proven in professional racing environments including NASCAR and drag racing, with testing exceeding two million cycles. By eliminating crankshaft torsional vibration, the Super Damper allows engines to accelerate faster, run smoother, and produce more reliable power throughout the RPM range.
