Product Description

The ATI 918049 Super Damper Harmonic Balancer is a high-performance crankshaft damper designed specifically for 2011-2024 Ford Mustang GT models equipped with the 5.0L Coyote V8. Featuring a 20% overdrive crank pulley, this balancer increases accessory drive speed while providing superior control of torsional crankshaft vibrations that can occur during aggressive driving or high-RPM operation.

Built to ATI's proven Super Damper design, the 918049 uses an internal balance elastomer system to protect critical engine components and improve durability under demanding conditions. The SFI 18.1 certification makes it suitable for track use, while the laser-etched 360° timing marks allow for precise tuning. Fitment is confirmed through the 2024 model year; 2025 coverage is unconfirmed at time of listing.
