ATI Performance Products ATI917793 Super Damper Harmonic Balancer

The ATI Performance Products ATI917793 Super Damper is a high-performance harmonic balancer engineered exclusively for demanding, high-RPM performance and racing engines. ATI's patented Super Damper technology is the industry standard for crankshaft vibration control in both street performance and sanctioned racing competition.

ATI Super Dampers use a precision elastomer O-ring system with computer-machined grooves in the steel inertia weight to maintain the correct durometer under all operating conditions. This design effectively eliminates torsional crankshaft vibrations that rob power, accelerate bearing wear, and can lead to catastrophic engine failure at elevated RPM.

Key Features:

• Patented Super Damper design developed exclusively for high-performance, high-RPM engines
• Exceeds SFI 18.1 specification for sanctioned NHRA and IHRA competition
• Tunable, rebuildable construction for long service life
• Computer-controlled, laser-engraved 360-degree timing marks for precise ignition timing
• Black zinc chromate finish for corrosion resistance
• Eliminates harmful torsional crankshaft vibrations across the full RPM range
• Inner and outer shells in aluminum or steel construction containing a precision steel inertia weight

ATI Super Dampers have been proven in Winston Cup competition over two million test cycles and in drag racing applications for over a decade, making the ATI917793 a trusted choice for serious engine builders seeking maximum reliability and performance.
