ATI Performance Products ATI916520 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI916520 Super Damper is a high-performance torsional crankshaft damper engineered to protect your engine from harmful harmonic vibrations. ATI's Super Dampers are a direct upgrade over factory harmonic balancers, designed to absorb and dissipate torsional crankshaft vibration across a wide RPM range — making them a popular choice for street performance, road racing, drag racing, and other high-output applications.

Unlike OEM rubber-bonded balancers that degrade over time and lose effectiveness at high RPM, ATI Super Dampers use a precision-machined billet aluminum housing with a bonded elastomer ring and inertia ring. This design provides consistent and reliable damping across varying operating temperatures and RPM ranges.

Key Features:

• Precision-machined from high-quality billet aluminum
• Elastomeric torsional damping element for broad RPM effectiveness
• Superior harmonic vibration absorption compared to OEM balancers
• Built to withstand the demands of high-performance and racing environments
• SFI 18.1 specification approval (typical for ATI Super Damper race units)
• Designed for correct balance and timing mark accuracy
• Direct-fit replacement for compatible applications

ATI Performance Products has been a trusted name in motorsports since 1966, and their Super Damper line is used by professional race teams and serious enthusiasts alike. The ATI916520 is built to the same exacting standards as all ATI dampers, delivering long-lasting protection and performance reliability.
