ATI Performance Products ATI916349 Super Damper Harmonic Balancer

The ATI Performance Products ATI916349 Super Damper is a precision-engineered torsional damper (harmonic balancer) designed to control crankshaft torsional vibrations, protect engine internals, and improve power output. ATI's Super Dampers are a benchmark in performance engine building, trusted by professional racers and engine builders across drag racing, road racing, marine, and high-performance street applications.

Unlike OEM rubber-bonded balancers that degrade over time and lose their damping effectiveness, the ATI Super Damper uses a precisely tuned elastomer ring sandwiched between an inner hub and outer inertia ring. This design provides consistent, repeatable damping across a broad RPM range, helping to extend crankshaft and bearing life while allowing the engine to safely reach higher RPM levels.

Key Features:

• Precision SFI-rated construction for sanctioned racing applications
• Elastomer damping ring for superior torsional vibration control
• Machined from high-quality billet steel or aluminum (application-specific)
• Timing marks laser-etched or stamped for accurate ignition timing
• Rebuildable and re-tunable design for long service life
• Manufactured in the USA by ATI Performance Products

ATI Super Dampers are SFI 18.1 certified where applicable and meet the requirements of most major sanctioning bodies. Whether you're building a dedicated race engine or a high-performance street machine, the ATI916349 delivers the reliability and precision that ATI Performance Products is known for worldwide.
