Sky's Ford Super Duty Shackle Reversal leaf spring conversion is built with longevity in mind. There is no 1/8 and 3/16ths steel in this kit! We only use USA made steel, laser cut and CNC formed for precise holes, no 1/8th inch of slop here! We are the first company to design the rear shackle hangers based off the kit being used with Ford Super Duty springs, moving the shackle pivot point forward to achieve a correct shackle angle thus improving ride quality even further. All kits come powder coated gloss black for a long lasting quality finish.
Kit is designed around the V code super duty springs, and will give a 4 inch lift, keeping nearly stock caster angles and much better shackle angle with new hangers. We have also started giving the option of a rear block kit that will bring the rear end up to about 1 inch higher than the front with this kit installed. See options below.
Currently with 1/4 inch spacers we have not found a need to cut the front bumper. 2 pr are included in the kit for extra spacing if needed.

3. Remove front tires, remove shocks, remove trac bar mount

6. Lower front axle enough to remove front shackles.
7. Install new front hanger , lining up the 5/8” bolts in hanger with factory bolt holes install spacer into frame opening and insert 5/8” bolt through holes in frame, new bracket, and spacer. Tighten bolt snug at this time . You will torque all hardware at the end of installation.Remove rear spring leaf bolt.
8.Measure 55.5” from center of rear spring bolt to center of new front spring bolt hole.Next remove shackle hanger. Install new shackle hangers, with supplied 1/2 inch hardware. It is best to start with one hole and make all the rest line up based on that point. Ford seems to be off as much as 3/8ths of an inch truck to truck.
9.Center punch and drill ½” holes in new front cross member locations as marked by ½” holes in shackle reversal. Install ½” bolts ,nuts , flat washers . Be sure to use red loc tite and torque to nominal specifications. Now is the time to replace the spring bushings if you plan to do so.

12. Check to make sure brake lines are not stretched. You may have to bend the hard line at the calipers toward the frame and/or bend down the tab that holds lines at frame
13. Install front bumper.
14 Install tires , raise the front of the vehicle and remove the jack stands place vehicle on ground and torque wheels to manufacture specs.
15. Remove upper trac arm bracket and install new fabricated drop down bracket. Reinstall factory pan hard bar, or new adjustable Sky's bar. It helps to use the steering when aligning all the holes. Simply start truck and turn left or right slightly to Align.
16. Bumper spacing, simply add spacers as needed to make bumper clear shackle reversal hanger. We are sure somewhere there is a truck that will need the bumper trimmed, worst case plan for this. Install bumper as removed.
17. Axle relocation plates. Depending on the location of the axle center line and size of tires being run, it may be necessary to move the axle forward slightly more. The axle relocation pads will move the axle either 5/8ths or 3/4 inch. The axle relocation pads will require die grinding, milling, etc of the top shock mount u bolt plates to allow the spring pin movement.
Sway bar drops are not provided, many people do not reinstall the sway bar as they feel with good shocks and the reversal it is no longer needed. If you wish to retain the front factory sway bar, you will need some .500 id tube to cut and sleeve the factory sway bar links.
