ATI Performance Products ATI916254M Super Damper Harmonic Balancer

ATI Performance Products ATI916254M is a high-performance Super Damper harmonic balancer engineered to reduce torsional vibration on high-output engines. ATI's Super Dampers are widely regarded as the gold standard in crankshaft vibration dampening, trusted by professional racers and serious performance enthusiasts alike.

ATI Super Dampers use a precision-tuned elastomer ring sandwiched between an inner hub and outer inertia ring to absorb and dissipate harmful crankshaft torsional vibrations. Unlike OEM rubber-bonded balancers that degrade over time, ATI's design is rebuildable and re-tunable for long-term reliability and consistent performance.

Key Features:

• Precision-machined billet aluminum and steel construction for superior strength and durability
• SFI 18.1 specification compliant — meets sanctioning body requirements for circle track, drag racing, and road racing
• Rebuildable and re-tunable elastomer design for long service life
• Laser-etched timing marks for accurate ignition timing
• Reduces harmful torsional crankshaft vibrations that can damage bearings, seals, and valve train components
• Available in multiple diameter and weight configurations to suit specific engine builds
• Manufactured in the USA by ATI Performance Products
