ATI Performance Products ATI917057 Super Damper Harmonic Balancer

The ATI Performance Products ATI917057 Super Damper is a high-performance torsional damper engineered to protect your engine from the destructive effects of crankshaft harmonics. Designed for racing and performance applications, ATI Super Dampers are the industry standard in torsional vibration control, trusted by professional racers and engine builders worldwide.

Unlike factory rubber-bonded harmonic balancers, ATI Super Dampers use a precision-machined billet aluminum shell with a specially tuned elastomer ring that more effectively absorbs and dissipates torsional vibration energy across a broad RPM range. This reduces stress on the crankshaft, bearings, and rotating assembly — extending engine life and improving power consistency.

Key Features:

• Precision billet aluminum construction for strength and light weight
• Tuned elastomer dampening ring for broad-spectrum vibration control
• SFI 18.1 certified for sanctioned racing events
• Neutral balance for accurate engine balancing
• Replaceable elastomer rings for long service life
• Manufactured in the USA to strict tolerances
• Includes timing marks for accurate ignition timing reference

ATI Super Dampers are a direct upgrade over OEM harmonic balancers in high-performance and race engines, providing superior crankshaft protection while meeting the SFI certification requirements mandated by most racing sanctioning bodies.
