ATI Performance Products ATI916776 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI916776 Super Damper is a high-performance torsional harmonic damper engineered to protect your engine's crankshaft from damaging harmonic vibrations. ATI's Super Dampers are the gold standard in crankshaft damper technology, trusted by professional racers and performance enthusiasts worldwide.

Unlike factory rubber-bonded harmonic balancers that degrade over time and lose damping effectiveness, ATI Super Dampers utilize a precision elastomer ring and steel inertia ring assembly for consistent, long-lasting torsional vibration control. This design not only extends crankshaft and bearing life but also helps reduce internal engine friction for improved power output.

Key Features:

• Precision-machined billet steel construction for strength and durability
• Elastomer-based torsional damping system for superior vibration control
• Resists heat, oil, and chemical degradation — unlike rubber OEM balancers
• Precision timing marks for accurate ignition timing reference
• SFI 18.1 certification (verify applicability for specific variant)
• Rebuildable and re-tunable design for long service life
• Manufactured in the USA by ATI Performance Products

ATI Super Dampers are a direct upgrade over stock harmonic balancers for high-performance street, strip, and racing applications. Proper torsional damping is critical in high-horsepower and high-RPM builds to prevent crankshaft fatigue failure and premature bearing wear.
