ATI Performance Products ATI916579 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI916579 Super Damper is a precision-engineered torsional crankshaft damper designed for high-performance and racing applications. ATI's Super Dampers are SFI 18.1 certified and built to replace the factory harmonic balancer with a unit capable of withstanding the extreme RPM and torsional forces generated by modified and race engines.

Unlike factory rubber-bonded balancers that degrade over time and lose effectiveness at high RPM, ATI Super Dampers use a precision-tuned inertia ring suspended in a viscous fluid or elastomer medium to effectively absorb and dampen harmful crankshaft torsional vibrations. This protects the crankshaft, bearings, and rotating assembly from fatigue damage.

Key Features:

• SFI 18.1 certified for sanctioned racing use
• Precision-machined billet steel or aluminum construction
• Tuned inertia ring for effective torsional vibration dampening across the RPM range
• Replaces OEM harmonic balancer with a performance-grade unit
• Laser-engraved timing marks for accurate ignition timing
• Resists heat, oil, and the harsh conditions of high-performance engines
• Reusable and rebuildable design for long service life

ATI Performance Products has been a trusted name in professional motorsports for decades, supplying Super Dampers to NASCAR, NHRA, and a wide range of circle track and road racing applications. The ATI916579 is built to the same exacting standards as ATI's race-proven components.
