ATI Performance Products ATI918869 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI918869 Super Damper is a high-performance elastomer harmonic balancer engineered to effectively dampen destructive crankshaft torsional vibrations. ATI Super Dampers are a direct upgrade over stock harmonic balancers, delivering superior vibration control that helps protect the crankshaft, bearings, and rotating assembly from stress-induced fatigue and failure.

ATI Super Dampers use a precision-machined billet aluminum or steel shell paired with a specially formulated elastomer ring that is tuned to absorb and dissipate the specific harmonic frequencies generated by your engine. Unlike OEM balancers, ATI dampers are designed to maintain their damping performance far longer without the rubber degradation that affects stock units over time.

Key Features:

• Precision-engineered to dampen crankshaft torsional vibration
• Billet construction for superior strength and durability
• Tuned elastomer ring for optimal vibration absorption
• Outperforms OEM harmonic balancers in demanding applications
• Designed for high-RPM street, strip, and racing use
• SFI certification (where applicable per application)
• Precision timing marks for accurate ignition timing

ATI Performance Products has been the industry leader in crankshaft damper technology for decades, and the ATI918869 Super Damper upholds that legacy of quality and performance. Ideal for performance builds where engine longevity and reliability under high-stress conditions are a priority.
