ATI Performance Products ATI917040EP Super Damper Harmonic Balancer

ATI Performance Products ATI917040EP is a high-performance Super Damper harmonic balancer engineered by ATI Performance Products, one of the most trusted names in professional racing and high-performance engine damper technology.

ATI Super Dampers are designed to replace factory harmonic balancers with a precision-engineered, elastomer-tuned torsional damper that reduces crankshaft torsional vibration — protecting the crankshaft, bearings, and rotating assembly at high RPM. Unlike OEM rubber-bonded balancers that degrade over time and are not tunable, ATI Super Dampers use a captured elastomer ring system that can be re-indexed and retuned as engine specifications change.

Key Features:

• Precision SFI-certified construction for sanctioned racing applications
• Captured elastomer tuning ring — rebuildable and re-indexable
• Reduces harmful crankshaft torsional vibration at high RPM
• CNC-machined from billet aluminum for strength and reduced rotating mass
• Compatible with timing accessories and front drive systems
• Direct replacement for OEM balancer in supported applications

ATI Performance Products has been a leader in torsional damper technology for decades, supplying components to NHRA, NASCAR, and professional engine builders worldwide. The ATI917040EP is built to the same exacting standards as ATI's full racing lineup.

Note: Please confirm fitment with ATI's application guide or your engine builder prior to installation.
