This kit is designed to allow the S-550 / S-650 suspension to bolt to a F-100 (34" wide rear frame) using the factory subframe mounts on the 2015-2023 Mustang S-550 and 2024+ S-650 rear suspension. It also integrates mounts for a 12” coil-over. This setup allows for an unmodified bed and much lower than stock ride height, as well as modern, brakes, suspension, and a limited slip differential. The kit uses the leaf spring bracket holes to locate the assembly (be careful not to mangle the holes when you are removing the factory rivets!) and bolts to the side and bottom of the frame rails. A small notch in the bottom flange of the frame rail is the only cutting you need to do (to clear the upper arm). You will need to drill some holes for installation, but the brackets act as templates to keep the install simple and straight forward. Kit contains all mounting brackets and hardware required to mount the 2014-2023 Mustang S-550 and 2024+ S-650 rear subframe to your F-100 frame. Coil-overs not included in kit.
