Note: Additional items may be needed to complete installation. You may want to include our Mustang II ride height adjusters (91034444) for installation with these IFS kits to fine tune your final ride height up to 2".
Note: If using these kits with Speedway or Heidts crossmembers for 1948-1956 Ford Pickups, 1955-1959 Chevy Pickups, or universal crossmembers for 27-1/2" - 33-1/2" frame widths, you will be required to purchase 2" Inner Tie Rod Extensions (91034345) or (91034346).
Note: Our Mustang II springs that we currently offer are all 13.5” long and require trimming to the length needed for each individual application. Weight rating changes as the spring is shortened. When installing in the vehicle the flat end goes up into the upper hat and the end with the “pigtail” goes down into the lower control arm. Spring is rotated when installing to position the pigtail properly. Springs TOO long will have a tendency to NOT sit properly on the lower arms and actually in some cases bow outward causing spring bind.
