ATI Performance Products ATI916951 Super Damper Harmonic Balancer

The ATI Performance Products ATI916951 Super Damper is a precision-engineered harmonic balancer (crankshaft damper) designed to reduce torsional vibration and protect your engine's crankshaft, bearings, and rotating assembly under high-performance and racing conditions. ATI Super Dampers are trusted by professional racers and engine builders worldwide for their superior vibration damping performance and durability compared to OEM rubber-bonded balancers.

Unlike factory harmonic balancers that rely on a rubber ring which can deteriorate over time and lose effectiveness, ATI Super Dampers use a precision-tuned inertia ring suspended in a specially formulated viscous fluid. This design continuously and automatically adjusts to changing harmonic frequencies across the full RPM range, providing consistent protection whether at idle or at peak power.

Key Features:

• Viscous fluid damping technology for consistent, broad-spectrum harmonic control
• Precision-machined billet steel construction for maximum strength and durability
• Correctly tuned inertia ring matched to specific engine application
• SFI 18.1 specification compliant for sanctioned racing events
• Improved protection for crankshaft, main bearings, and front cover seals
• Laser-engraved timing marks for accurate ignition timing
• Outperforms OEM rubber-bonded balancers in sustained high-RPM applications

ATI Performance Products has been manufacturing high-quality performance drivetrain components since 1966. The ATI916951 Super Damper is built to handle the demands of street performance, strip racing, road racing, and circle track applications, making it an essential upgrade for any serious performance or racing engine build.
