ATI Performance Products ATI917830 Super Damper Standard Harmonic Balancer

The ATI Performance Products ATI917830 Super Damper is a patented high-performance crankshaft harmonic balancer engineered exclusively for high-performance and racing engines. Unlike OEM rubber-bonded dampers, the ATI Super Damper uses a proven elastomer O-ring design that effectively eliminates torsional crankshaft vibrations across the entire RPM range — protecting your engine and freeing up horsepower.

Key Features:

• Patented elastomer O-ring design eliminates torsional crankshaft vibrations at all RPM
• Inner and outer shells available in aluminum or steel, containing a precision steel inertia weight
• Computer-machined grooves in the inertia weight retain proper durometer O-rings, dyno tested for each application
• Exceeds SFI 18.1 specifications — SFI manufacturer certified
• Black zinc chromate finished shells for corrosion resistance
• Computer-controlled, laser-engraved 360° timing marks for precise tuning
• Tunable, rebuildable, and serviceable — O-rings replaceable to restore like-new performance
• Replaceable bolt-in crank hub design
• OEM equipment on a variety of crate engines

The ATI Super Damper's O-ring design has been validated in competition, with durability tested to millions of cycles at high RPM in both oval and drag racing environments. The unit exceeds SFI 18.1 specs and is an ideal upgrade for street performance, strip, or road race applications. Supercharger and power steering drive pulleys are available separately for select applications.
