ATI Performance Products ATI917208 Super Damper Harmonic Balancer

The ATI Performance Products ATI917208 Super Damper is a high-performance crankshaft harmonic balancer engineered to reduce torsional vibration and protect engine components in demanding performance and racing applications. ATI Super Dampers are widely regarded as the gold standard in harmonic dampening, offering superior protection over stock rubber-bonded balancers.

Unlike OEM balancers that rely on a rubber ring bonded between inner and outer rings — which can slip, degrade, or fail under heat and stress — ATI Super Dampers use a precision-machined, elastomer-dampened design that maintains accurate timing marks and delivers consistent performance under extreme conditions.

Key Features:

• Precision SFI-certified construction for performance and racing use
• Elastomer dampening ring resists heat, chemicals, and age-related degradation
• Laser-etched or stamped timing marks for accurate ignition timing
• Precision-machined from billet steel or aluminum for superior balance
• Replaces worn or under-performing OEM harmonic balancers
• Compatible with performance and racing belt drive and timing cover setups
• Helps prevent crankshaft and bearing damage caused by torsional vibration
