ATI Performance Products ATI916720 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI916720 Super Damper is a high-performance torsional crankshaft damper engineered to protect your engine from harmful harmonic vibrations that can destroy crankshafts, bearings, and other rotating assembly components. ATI Super Dampers are the gold standard in motorsports and high-performance street applications, trusted by professional racers and engine builders worldwide.

Unlike factory rubber-bonded OEM balancers that degrade over time and fail under high-RPM stress, the ATI Super Damper uses a precision-machined elastomer ring within a billet aluminum or steel shell to provide consistent, tunable damping across a wide RPM range. The result is a longer engine life, more stable ignition timing, and improved overall performance.

Key Features:

• SFI 18.1 certified for sanctioned racing competition
• Precision-machined billet construction for superior balance and durability
• Elastomer damping ring resists heat, oil, and age-related degradation
• Multiple timing marks for accurate ignition timing reference
• Replaces factory harmonic balancer with a performance-grade upgrade
• Designed and manufactured in the USA by ATI Performance Products

ATI Super Dampers are engineered for longevity and reliability under the most demanding conditions, making the ATI916720 an ideal choice for performance street builds, drag racing, road racing, and circle track applications.
