ST Suspension has teamed up with KW Suspension to design these high quality adjustable twin-tube coilovers for your 2015-2017 Mustang GT or EcoBoost. If you are looking to lower your stance and improve your driving dynamics and handling on your Mustang then look no further than this ST Suspension S550 Mustang ST-X Adjustable Coilover Kit.

ST Suspension's coilover kit for your S550 replaces your factory OE shocks, struts, and springs. Installing this coilover kit onto your 2015-2017 Mustang GT or EcoBoost will deliver a more sporty handling by reducing body roll during spring compression. You will also notice an increase in steering response due to the stiffer spring rates created by this ST Suspension coilover kit. ST Suspension has engineered these coilovers to give you adjustability in ride height using a polyamide ring located on the strut. You can finely tune your ride height to your liking, front height can be adjusted from 1.2" to 2" and rear height can be adjusted from. 8" to 1.6".

These ST-X adjustable coilovers from ST Suspension features galvanized, multiple-sealed dampers with polyamide rings for adjustability. Both front and rear damper housings on this kit are made from low-friction and pressure resistant housing featuring chrome-plated piston rods for maximum longevity. A mono block guide and ST seal package ensures that the twin-tube dampers remain free of dirt particles.
