ATI Performance Products ATI918955 Super Damper Harmonic Balancer

The ATI Performance Products ATI918955 Super Damper is a high-performance harmonic balancer engineered to reduce crankshaft torsional vibration, protect engine internals, and optimize power output. ATI Super Dampers are trusted by professional racers and serious performance enthusiasts across drag racing, road racing, and high-performance street applications.

Unlike factory rubber-bonded dampers that degrade over time and lose their dampening effectiveness, ATI Super Dampers use a precision-machined, multi-ring elastomer design that maintains consistent performance under extreme heat and RPM loads. This design absorbs and dissipates harmful crankshaft harmonics that can lead to bearing wear, crankshaft fatigue, and power loss.

Key Features:

• Precision SFI-certified construction for sanctioned racing use
• Multi-elastomer dampening rings for superior harmonic absorption
• Precision-machined billet aluminum or steel housing depending on application
• Accurate timing marks for precise ignition tuning
• Direct OEM replacement fitment with performance upgrade benefits
• Resists heat, oil, and chemical exposure better than factory units
• Rebuildable and re-indexable design for long service life

The ATI918955 Super Damper is designed to be a direct bolt-on replacement, making installation straightforward for experienced builders. It is engineered to maintain crankshaft integrity at elevated RPMs where factory harmonic balancers are no longer adequate, making it an ideal upgrade for any serious performance or racing build.
