    Choose Your Drop. Lowering your 2015-2019 Mustang's suspension gives it a more crouched, aggressive stance, like a predator ready to pounce. Additionally, it provides improved handling and cornering. The ST Suspension ST-X Height Adjustable Coilover Kit gives you the ability to fine-tune exactly how much the front and rear are lowered. The threaded shock bodies enable customizing body drop between 1.2"-2" for the front and 0.8"-1.6" in the rear. At the same time, the ST-X kit provides harmonic damping and a comfortable spring rate for smooth, pleasant ride quality. You can adjust the rebound between soft and sporty as desired. These coilovers cut rear squat, nosedive and body roll.

    Elite Build. The ST Suspension ST-X Height Adjustable Coilover Kit features tough, annealed and shot-blasted coil springs and twin-tube damping shock absorbers. The strut housing is steel, zinc-plated to defy corrosion, while the spring caps and seats are composite polyamide which absorbs road noise and vibration. Each shock absorber features an external adjustment wheel to dial in ride height. Made in the USA, this kit is covered by a standard manufacturer's 5 year limited warranty.

    Application. The ST Suspension ST-X Height Adjustable Coilover Kit can be used on any 2015-2019 Ford Mustang that is not equipped with the MagneRide Suspension.

    1 Top Rated Question

    What are the spring rates for this coil over kit in comparison to other kits? My biggest concern is ride quality.

    • The ST Suspension ST-X Height Adjustable Coilover Kit utilizes progressive rate springs. Unfortunately they do not provide specific spring rates, however these are tied for the nicest riding coil overs we offer with the Roush Single Adjustable Coil Over Kit.

      Love the way it just grips when I do a quick pull. Gives my mustang a more aggressive look as well.

      One of the best!

      This is the best coilover kit I have found since it improves the handling and ride comfort of the ride. Thanks AM.
