ATI Performance Products ATI916972 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI916972 Super Damper is a high-performance torsional crankshaft damper engineered to reduce harmful torsional vibrations that can damage crankshafts, bearings, and other rotating engine components. ATI Super Dampers are trusted by professional racers and performance enthusiasts across drag racing, road racing, and high-performance street applications.

Unlike stock OEM harmonic balancers that use a rubber ring bond which can degrade and slip over time, ATI Super Dampers utilize a precision-tuned elastomer ring within a billet aluminum housing, providing consistent and reliable vibration dampening throughout the RPM range. The result is improved engine longevity, more consistent ignition timing, and enhanced overall performance.

Key Features:

• Precision-machined billet aluminum construction for strength and reduced weight
• Elastomer-based torsional damping system — no rubber bond to slip or degrade
• SFI 18.1 specification certified for sanctioned racing use
• Laser-etched timing marks for accurate ignition timing
• Designed as a direct OEM replacement with performance upgrade benefits
• Suitable for high-RPM racing and performance street engines
• Made in the USA by ATI Performance Products

ATI Super Dampers are designed and manufactured in the USA and meet SFI 18.1 specifications, making them legal for use in most sanctioned drag racing events. Whether building a dedicated race engine or a high-performance street machine, the ATI916972 Super Damper delivers the protection and precision your engine demands.
