ATI Performance Products ATI917071-70 Super Damper Harmonic Balancer

ATI Performance Products ATI917071-70 is a high-performance Super Damper harmonic balancer engineered to reduce crankshaft torsional vibration in high-output and racing engines. ATI's Super Damper series is widely regarded as the industry standard in professional motorsports and performance street applications, offering superior vibration damping compared to OEM rubber-bonded balancers.

ATI Super Dampers utilize a precision-machined billet steel housing with a specially tuned elastomer ring that is specifically calibrated for high-RPM operation. Unlike factory balancers that can deteriorate over time and at elevated RPMs, ATI's design maintains its tuned frequency characteristics throughout the life of the component, protecting critical engine components from harmful harmonic resonance.

Key Features:

• Precision billet steel construction for maximum durability
• Tuned elastomer damping ring calibrated for high-performance and racing applications
• Superior torsional vibration control compared to OEM rubber balancers
• SFI 18.1 specification compliant — required for many sanctioned race events
• Maintains tuned damping frequency across the full RPM range
• Precision machined for accurate balance and minimal runout
• Direct OEM replacement fitment with performance upgrade benefits

ATI Performance Products has been a trusted name in professional racing since 1966, supplying Super Dampers and transmission components to top-level motorsports programs across NHRA, NASCAR, and beyond. The ATI917071-70 is built to the same exacting standards used in professional competition.
