ATI Performance Products ATI916314 Super Damper Harmonic Balancer

The ATI Performance Products ATI916314 Super Damper is a high-performance harmonic balancer engineered exclusively for demanding race and street applications. ATI's patented Super Damper design is the only crankshaft damper developed specifically for high-RPM performance engines operating at 6,000 RPM and beyond, making it the preferred choice of professional racers and serious enthusiasts alike.

Unlike conventional rubber-bonded harmonic balancers that degrade over time and fail under extreme heat and RPM, the ATI Super Damper uses precision-fit elastomeric O-rings retained in computer-machined grooves on a steel inertia weight. This design delivers consistent, tunable torsional vibration damping across the full RPM range, protecting crankshaft bearings, reducing engine wear, and optimizing power delivery.

Key Features:

• Patented Super Damper design developed exclusively for high-performance and racing engines
• Steel inertia weight with computer-machined grooves for proper durometer O-ring retention
• Inner and outer shells available in aluminum or steel construction
• Black zinc chromate finish with computer-controlled, laser-engraved 360-degree timing marks
• Tested in Winston Cup competition over two million cycles
• Exceeds SFI 18.1 specifications — approved for NHRA and IHRA competition
• Manufactured and precision-machined in the USA

The ATI916314 Super Damper is a direct-fit performance upgrade that eliminates harmful crankshaft harmonics, extending engine component life while freeing up measurable horsepower and torque. Whether on the track or the street, ATI Super Dampers deliver race-proven reliability and performance.
