ATI Performance Products ATI916760 Super Damper Harmonic Balancer

The ATI Performance Products ATI916760 Super Damper is a high-performance crankshaft harmonic balancer engineered for street, strip, and race applications. ATI's patented Super Damper design is the only crankshaft damper developed exclusively for high-RPM performance engines, providing superior protection against destructive torsional crankshaft vibrations that can rob power and shorten engine life.

Key Features:

• Patented elastomer O-ring design — steel inertia weight features computer-machined grooves retaining precision durometer O-rings, dyno tested for each specific application
• Exceeds SFI 18.1 specifications — tested to over two million cycles in NASCAR Cup Series competition and proven in drag racing engines for over ten years
• Inner and outer shells available in aluminum or steel construction to contain the steel inertia weight
• Black zinc chromate finish for corrosion resistance and lasting durability
• Computer-controlled, laser-engraved 360-degree timing marks for precise ignition timing
• Tunable and rebuildable — can be restored to new specifications with replacement O-rings
• Effective at eliminating torsional vibrations across all RPM ranges, especially above 6,000 RPM

ATI Super Dampers are OEM equipment on a variety of high-performance crate engines and are trusted by professional racers across multiple motorsport disciplines. The Super Damper design functions as two dampers in one, providing multi-frequency vibration attenuation for comprehensive crankshaft protection. Supercharger and power steering drive pulleys are available for select applications.
