ATI Performance Products Super Damper Harmonic Balancer SFI

The ATI Performance Products Super Damper harmonic balancer is an SFI-rated crankshaft damper built to control torsional vibration and protect the engine in high-performance, racing, and street/strip applications. Also known as a crank damper or vibration damper, it replaces the factory balancer to improve durability and engine smoothness.

Key Features:

• SFI-certified construction for racing use, built to meet SFI Spec 18.1 requirements
• Machined steel and aluminum design that combines a strong hub with a precision-machined outer housing
• Elastomer-isolated damping reduces crankshaft harmonics that can lead to bearing wear, timing inconsistency, and component fatigue
• Precision balanced to help the engine run smoothly at high RPM
• Timing marks for accurate ignition timing setup
• Multiple configurations are offered across the Super Damper line for different engine families and accessory drive setups

ATI is well known in motorsports for its crankshaft dampers, transmissions, and drivetrain components. The Super Damper line is designed for racers and enthusiasts who want a reliable, quality balancer that protects the engine under heavy load and high RPM.
