ATI Performance Products ATI916301 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI916301 Super Damper is a high-performance elastomer-style crankshaft harmonic balancer engineered to reduce torsional vibration and protect your engine's crankshaft, bearings, and rotating assembly under demanding conditions. Designed as a direct upgrade over OEM balancers, ATI Super Dampers are a trusted choice in circle track, drag racing, road racing, and high-performance street applications.

ATI Super Dampers use a precision-machined billet aluminum shell bonded to a high-inertia steel ring via a specially formulated elastomer, tuned specifically to the resonant frequency of the engine's crankshaft. This damping action absorbs destructive torsional harmonics that can lead to premature wear or catastrophic failure of the crankshaft and other drivetrain components.

Key Features:

• Billet aluminum construction for reduced rotational mass and superior strength
• Precision-tuned elastomer bonding matched to engine-specific torsional frequencies
• SFI 18.1 specification certified for sanctioned race use
• Replaces OEM harmonic balancer for a direct-fit installation
• Includes timing marks for accurate ignition timing reference
• Compatible with standard front accessory drive and timing components
• Reusable and rebuildable design for long service life

ATI Performance Products has been manufacturing Super Dampers since 1966 and is the industry standard in crankshaft damper technology. The ATI916301 is built to withstand the rigors of high-RPM racing environments while remaining streetable for performance enthusiasts.
