Lowered Ride Height

Get rid of the ugly wheel gap on your S550 with the help of these 2015-2022 Mustang V6 or Ecoboost Eibach Pro-Kit lowering springs! These springs lower your S550 on average by approximately 1.1" in the front and 1.0" in the rear. The Pro-Kit springs feature a specific rate for firmer ride quality and a moderate increase in spring rate. This kit can be used with factory shocks and struts but upgrading to performance shocks & struts is recommended for maximum performance benefit.

Increased Suspension Performance

Every Eibach Pro-Kit is designed and tested by a suspension engineer and performance driving professional - to offer aggressive good looks and high-performance handling - the best of both worlds without compromising safety or ride quality. By using this proprietary, specific rate spring design, the Pro-Kit provides the ultimate balance that will take your passion for driving to a whole new level.

    About This Brand

    Eibach - "The Will to Win"
    Eibach makes the finest performance suspension products in the world for your Mustang or Ford Lightning. When other suspension components sag, wear out, or create sloppy handling or a bone-crushing ride, top street tuners—like top race teams, from F1 to WRC, from Le Mans to NASCAR—inevitably turn to Eibach.

    Eibach integrates the exact same technology in their street springs as they do in their legendary race springs. Eibach uses the world´s finest Hi-Ten spring steel, produced to exceedingly precise tolerances. Eibach uses world-renowned German CNC coilers, as well as many unique machines engineered and built specifically by Eibach—simply state-of-the-art technology, in every step of the manufacturing process. Shop LatemodelRestoration.com for your Eibach Mustang lowering springs, suspension kits, and sway bars.
