ATI Performance Products ATI917058 Super Damper Harmonic Balancer

The ATI Performance Products ATI917058 Super Damper is a high-performance torsional vibration damper engineered for demanding street, strip, and racing applications. ATI Super Dampers are manufactured in the USA and are widely regarded as the industry standard in harmonic balancer technology, providing superior crankshaft protection compared to OEM rubber-bonded balancers.

ATI Super Dampers use a precision-machined billet steel shell filled with a viscous fluid and a dedicated inertia ring, which absorbs and dissipates harmful torsional vibrations generated by the crankshaft. This design maintains engine reliability, reduces internal component wear, and can contribute to improved power output by allowing the engine to rev more freely.

Key Features:

• Billet steel construction for maximum durability and longevity
• Viscous fluid dampening technology — more effective than OEM elastomer designs
• Precision SFI-rated design suitable for sanctioned racing events
• Laser-engraved timing marks for accurate ignition timing
• Replaces worn or inadequate factory harmonic balancers
• Manufactured in the USA to strict quality standards
• Bolt-on installation compatible with stock and modified engines

ATI Super Dampers are trusted by professional racers and engine builders alike. The ATI917058 is designed as a direct-fit performance upgrade, protecting your rotating assembly and supporting consistent engine performance under high-RPM and high-load conditions.
