ATI Performance Products ATI950205 Super Damper Harmonic Balancer

The ATI Performance Products ATI950205 Super Damper is a high-performance torsional vibration damper (harmonic balancer) engineered to protect your engine's crankshaft from destructive harmonic vibrations under high-RPM and high-load conditions. ATI Super Dampers are trusted by professional racers and serious performance enthusiasts across drag racing, road racing, and high-performance street applications.

Unlike OEM rubber-bonded balancers that degrade over time and lose their damping effectiveness, ATI Super Dampers use a precision-machined aluminum housing with an inertia ring suspended in a viscous fluid or elastomer medium. This design maintains consistent damping characteristics across a wide RPM range, helping to extend crankshaft and engine component life.

Key Features:

• Precision-machined billet aluminum construction for durability and weight reduction
• Viscous or elastomer damping mechanism for reliable, long-lasting performance
• SFI 18.1 certified for sanctioned racing applications
• Replacement for worn or failed OEM harmonic balancer
• Laser-engraved timing marks for accurate ignition timing
• Designed for high-RPM performance use
• Corrosion-resistant finish

The ATI950205 Super Damper is a direct-fit performance upgrade that delivers superior crankshaft protection compared to stock units, making it an essential component for any serious engine build.
