ATI Performance Products ATI916548 Super Damper Harmonic Balancer

The ATI Performance Products ATI916548 Super Damper is a high-performance harmonic balancer engineered for high-RPM race and street performance engines. ATI's patented Super Damper design is the only crankshaft damper developed exclusively for high-performance applications, providing superior torsional vibration damping to protect crankshaft bearings and extend engine life.

Unlike conventional rubber-bonded OEM harmonic balancers, the ATI Super Damper uses precision-machined elastomer O-rings seated in computer-machined grooves on a steel inertia weight. This design maintains consistent damping performance across a wide RPM range and will not degrade or fail like bonded-rubber units under sustained high-RPM use.

Key Features:

• Patented Super Damper design engineered exclusively for high-performance engines
• Steel inertia weight with computer-machined O-ring grooves for consistent damping
• Aluminum or steel inner and outer shell construction for strength and reduced weight
• Black zinc chromate finish for corrosion resistance
• Computer-controlled, laser-engraved 360-degree timing marks for precise ignition timing
• SFI 18.1 certified for NHRA and IHRA sanctioned competition
• Tested in excess of two million cycles under Winston Cup and drag racing conditions

The ATI Super Damper is manufactured in-house at ATI's facility in Gwynn Oak, Maryland using CNC machining for total quality control. It is a direct upgrade over OEM harmonic balancers for performance builds requiring maximum reliability and precision at sustained high RPM.
