Shifteck is proud to release our IRS Stabilization Kit for the 2015+ Mustang GT350, GT, EcoBoost, and V6 (no convertibles). Our steel braces are coated for longevity.

They provide increased rigidity in the rear suspension of the S550, reduce wheel hop, and provide for a better feel and more driver confidence. All hardware is included for install.

We manufacture these in the USA and back them with our standard "No Questions Asked" lifetime warranty against workmanship.

They are in stock and ready to ship.
