Improves Handling Performance

Are you an S550 or EcoBoost Mustang owner that is looking for a great ride on the street and a significant increase in performance when putting your Pony through its paces? If so, you need to upgrade to a set of RTR Tactical Performance Lowering Springs. RTR Springs not only lower your Mustang, but they also feature proprietary street tested and track proved progressive spring rates for performance handling. These Springs were engineered to work with both base and performance pack dampers. However, in order to experience the maximum performance these Springs can offer, they should be installed along with RTR's matching Tactical Performance Adjustable Dampers and Sway Bars.

Sleek Muscle Car Stance

Not only does a set of RTR Tactical Performance Lowering Springs improve the handling performance of your Mustang, but they also improve its overall appearance. By lowering the ride height 1.1" up front and 0.8" in the rear these RTR Performance Springs will eliminate that huge tire to fender gap, for a sleek muscle car stance without the rear sag that other kits have when they lower the front and rear the same amount.

Clears Stock and Aftermarket Wheels & Tires

These lowering springs were engineered to be compatible with your factory size wheels and tires, as well as AmericanMuscle's pre-configured wheel and tire combo kits (specific to your generation), to assure proper clearance with no rubbing issues.


This set of four RTR Tactical Performance Lowering Springs was developed to create the perfect drop-in regards to both appearance and performance and have been specifically designed for use in 2015 - 2022 Fastback GT and EcoBoost Mustangs.

Technical Note

The Springs are not compatible with vehicles equipped with the MagneRide Suspension.
