ATI Performance Products ATI916920 Super Damper Harmonic Balancer

The ATI Performance Products ATI916920 Super Damper is a high-performance torsional vibration damper (harmonic balancer) engineered for demanding street and motorsport applications. ATI Super Dampers are manufactured from billet aluminum with precision-machined inertia rings and feature ATI's proven elastomer damping technology, effectively absorbing and dissipating crankshaft torsional vibrations to protect engine components and maximize power output.

Key Features:

• Precision billet aluminum construction for strength and light weight
• Multi-ring elastomer damping system controls torsional vibration across a wide RPM range
• SFI 18.1 certified for sanctioned racing applications
• Serviceable and rebuildable design — elastomers and rings can be replaced
• Precision laser-etched timing marks for accurate ignition timing
• Provides additional belt drive surface options for racing accessory drives
• Direct OEM replacement fitment with performance upgrade benefits

Unlike bonded rubber OEM-style dampers that degrade over time and can fail catastrophically, the ATI Super Damper uses a replaceable elastomer system that maintains consistent damping performance over its service life. This makes it a preferred choice for high-revving, high-horsepower builds where crankshaft protection and longevity are critical.
