ATI Performance Products ATI916997 Super Damper Harmonic Balancer

The ATI Performance Products ATI916997 Super Damper is a high-performance crankshaft harmonic balancer engineered for racing and high-performance street applications. ATI's Super Dampers are widely recognized as the industry standard in torsional vibration damping, protecting crankshafts from the destructive harmonic frequencies generated under high-RPM and high-horsepower conditions.

Unlike factory rubber-bonded balancers that can deteriorate over time and fail at high RPM, ATI Super Dampers utilize a precision-machined billet aluminum shell with an inertia ring and elastomer tuning bands specifically calibrated for the application. This design provides consistent, reliable damping across a broad RPM range while maintaining dimensional stability under extreme heat and stress.

Key Features:

• Precision billet aluminum construction for strength and weight reduction
• Tuned elastomer dampening rings for superior torsional vibration control
• Designed to protect crankshafts from harmonic stress fractures
• Compatible with SFI-spec requirements common in sanctioned racing
• Replaces OEM harmonic balancer with a performance-engineered alternative
• Manufactured in the USA by ATI Performance Products

ATI Performance Products has been a trusted name in performance drivetrain components since 1966, producing dampers, torque converters, and transmissions for motorsport and enthusiast applications. The ATI916997 Super Damper is built to withstand the demands of forced induction, nitrous, and naturally aspirated high-performance builds.
