Product Description

The ATI 918053 Super Damper Harmonic Balancer is a performance-focused upgrade for 2011-2024 Ford Mustang GT models equipped with the 5.0L Coyote V8. Featuring a 10% underdrive crank pulley, this balancer reduces accessory drive speed to decrease parasitic loss, helping free up horsepower while maintaining proper harmonic control.

Built using ATI's proven Super Damper elastomer design, the 918053 protects the crankshaft and internal engine components from damaging torsional vibrations during high-RPM operation. SFI 18.1 certification makes it suitable for track use, while the laser-etched 360° timing marks support accurate tuning. Fitment is confirmed through the 2024 model year; 2025 coverage is unconfirmed at time of listing.
