ATI Performance Products ATI917339 Super Damper Harmonic Balancer

The ATI Performance Products ATI917339 Super Damper is a precision-engineered torsional crankshaft damper designed for high-performance and racing applications. ATI's Super Damper series is widely regarded as the industry standard in crankshaft vibration damping, protecting engine internals from the destructive harmonic vibrations generated under high-RPM and high-horsepower conditions.

Unlike OEM rubber-bonded balancers that degrade over time and lose effectiveness, ATI Super Dampers utilize a precision-machined elastomer ring in a controlled housing that maintains consistent damping characteristics across a wide RPM range. This design helps extend crankshaft and engine life while also providing a stable platform for accessory drive pulleys.

Key Features:

• Precision SFI-rated torsional damper construction
• Machined from high-strength billet steel or aluminum for superior durability
• Elastomer-based damping element maintains consistent performance over time
• Replaces factory harmonic balancer for improved crankshaft protection
• Suitable for street performance, strip, and road racing applications
• Manufactured by ATI Performance Products — an industry leader in performance drivetrain components

ATI Performance Products has been engineering championship-winning performance components since 1966. The Super Damper line is trusted by professional racers and performance enthusiasts alike for its proven ability to reduce crankshaft harmonics and protect engine investments at every level of competition.
