ATI Performance Products Super Damper Harmonic Balancer

The ATI Performance Products Super Damper Harmonic Balancer (also called a harmonic damper or crankshaft damper) is built to control torsional vibration in high-performance and racing engines. It mounts to the front of the crankshaft and absorbs the vibrations that build up as the engine runs. This helps protect the crankshaft, bearings, and valvetrain from fatigue and wear.

Key Features:

• Uses a machined steel or aluminum hub and outer shell with an internal elastomer-free design, which helps it stay stable under heat and high RPM
• Reduces crankshaft torsional vibration to help protect engine components and support power output
• Built for street performance, drag racing, circle track, and other demanding motorsports use
• Precision machined for accurate balance and a consistent fit
• Offered in a range of configurations to suit different engine families and applications

ATI Performance Products has made crankshaft dampers, transmissions, and torque converters for motorsports for many years. The Super Damper line carries that experience into a durable harmonic balancer that helps protect high-output engines. Select the child item that matches your engine application.
