ATI Performance Products ATI917078 Super Damper Harmonic Balancer

The ATI Performance Products ATI917078 Super Damper is a high-performance harmonic balancer engineered exclusively for high-RPM performance and racing engines. ATI's patented Super Damper design is widely regarded as the gold standard in crankshaft vibration damping, protecting your engine from destructive torsional harmonics that can cause premature wear or catastrophic failure at elevated RPM.

Key Features:

• Patented Super Damper design developed exclusively for high-performance engines operating at 6,000+ RPM
• Steel inertia weight features eight computer-machined grooves that retain precision durometer O-rings for consistent, reliable damping
• Inner and outer shells constructed of aluminum or steel to securely contain the inertia weight assembly
• Black zinc chromate finish with computer-controlled, laser-engraved 360-degree timing marks for accurate ignition timing
• Tested to exceed SFI 18.1 specifications — validated in Winston Cup competition over two million cycles
• Unlike bonded rubber OEM-style balancers, ATI's elastomer O-ring design resists heat, oil, and aging for long-term performance reliability
• Sold individually

The ATI Super Damper series is trusted by professional drag racers, road racers, and serious street performance enthusiasts worldwide. Unlike factory harmonic balancers that rely on a bonded rubber ring susceptible to deterioration, the ATI Super Damper uses a free-floating inertia ring retained by precision elastomer O-rings, providing superior and consistent harmonic damping across the RPM range.
