ATI Performance Products ATI916973 Super Damper Harmonic Balancer

The ATI Performance Products ATI916973 Super Damper is a high-performance harmonic balancer engineered for demanding race and street applications. ATI's patented Super Damper design is the only crankshaft damper developed exclusively for high-RPM performance engines, making it the go-to choice for serious engine builders and racers.

Each combustion event generates a torsional vibration spike that twists and rebounds the crankshaft. Left uncontrolled, these harmonic vibrations can cause accelerated bearing wear and crankshaft fatigue. The ATI Super Damper's proven elastomer O-ring system absorbs and dissipates these destructive forces across the full RPM range, protecting internal engine components and delivering smoother power output.

Key Features:

• Patented Super Damper design built exclusively for high-performance and racing engines
• Steel inertia weight with eight computer-machined grooves retaining precision-matched durometer O-rings
• Aluminum and/or steel inner and outer shells for durability and weight optimization
• Black zinc chromate finish for corrosion resistance
• Computer-controlled, laser-engraved 360-degree timing marks for precise tuning
• Exceeds SFI 18.1 specifications — tested in Winston Cup competition over two million cycles
• Manufactured and dyno-tested in the USA at ATI's facility near Baltimore, Maryland

ATI Performance Products has over 50 years of experience designing and manufacturing performance driveline components. The Super Damper line is trusted by professional drag racers, road racers, and high-performance street enthusiasts worldwide.
