ATI Performance Products ATI916127 Super Damper Harmonic Balancer

The ATI Performance Products ATI916127 Super Damper is a high-performance, SFI-certified torsional harmonic damper engineered to replace the factory crankshaft balancer on performance and racing engines. ATI Super Dampers are the gold standard in crankshaft vibration damping, trusted by professional racers and serious enthusiasts across drag racing, road racing, and high-performance street applications.

Unlike traditional rubber-bonded OEM balancers that degrade over time and lose damping effectiveness under high RPM stress, the ATI Super Damper uses a precision-machined, multi-piece design with an elastomer ring specifically tuned to absorb and dissipate torsional crankshaft vibrations. This protects the crankshaft, front timing components, and accessory drive systems from harmful harmonic resonance.

Key Features:

• SFI 18.1 Certified — meets sanctioning body requirements for competition use
• Precision CNC-machined from high-strength billet steel or aluminum (application-specific)
• Tuned elastomer dampening ring for broad RPM harmonic control
• Replaceable and re-tunable damper rings available for changing engine configurations
• Accepts ATI mud plug and front seal for complete sealing
• Machined timing marks for accurate ignition timing reference
• Direct bolt-on replacement — no special tools required beyond standard installation practices
• Compatible with ATI's full line of front accessory drive pulleys and gilmer drive systems

ATI Performance Products has been manufacturing precision powertrain components in the USA since 1966. The Super Damper line is engineered and assembled in-house to exacting tolerances, making the ATI916127 a reliable, competition-proven upgrade for any performance build.
