ATI Performance Products ATI917456 Super Damper Harmonic Balancer

ATI Performance Products ATI917456 is a high-performance Super Damper harmonic balancer engineered to reduce torsional vibration in high-output and racing engines. ATI's Super Dampers use a elastomer-bonded inertia ring design — the same proven technology trusted by professional racers across NASCAR, NHRA, and road racing — to protect crankshafts and rotating assemblies from damaging harmonic resonance.

Key Features:

• Multi-ring elastomer damper design for superior torsional vibration control
• Precision SFI-certified construction for sanctioned racing applications
• Manufactured from high-strength billet aluminum for reduced rotating mass
• Laser-etched timing marks for precise ignition timing reference
• Designed to outperform OEM rubber-bonded balancers under high-RPM and high-heat conditions
• Compatible with ATI's full line of timing pointers and accessories

ATI Super Dampers are manufactured in the USA and are a direct upgrade over factory harmonic balancers for performance street, strip, and competition builds. Always verify SFI certification requirements for your specific sanctioning body before installation.
