The ST-XTA dampening technology used in this coilover kit allows you to make your suspension stiffer or softer depending on driving conditions, and can be easily adjusted via the nut at the end of the chrome piston rod. Stiffen your dampening to get more stability and reduced body roll out of your Mustang. Soften the dampening and your S550 will feel more comfortable for daily driving. The aluminum top mounts on these dampers also feature a built-in camber and caster adjustment which can be tuned to your driving needs.

These ST-XTA 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.
