ATI Performance Products ATI917455 Super Damper Harmonic Balancer

The ATI Performance Products ATI917455 is a precision-engineered Super Damper harmonic balancer designed to protect your engine from torsional vibration damage. ATI's Super Damper series is the gold standard in aftermarket harmonic balancers, trusted by professional racers and performance enthusiasts across drag racing, road racing, and high-performance street applications.

Unlike factory rubber-bonded balancers that degrade over time and under heat, the ATI Super Damper uses a precision-machined, elastomer-tuned design that maintains consistent damping characteristics across a wide RPM range. The result is reduced crankshaft stress, extended engine life, and more accurate ignition timing.

Key Features:

• Precision SFI-certified construction for sanctioned racing applications
• Elastomer damping element tuned for specific engine applications
• Precision-machined billet steel or aluminum housing for strength and durability
• Accurate timing marks for precise ignition timing setup
• Replacement of worn or failed OEM rubber-bonded harmonic balancers
• Designed and manufactured in the USA by ATI Performance Products
