Do they make a leveling kit for my 2003 f150 King ranch Supercrew 4x4?

 

You don't need one. Your truck has torsion bar suspension. You can easily increase the preload on your torsion bars to level your truck. The only "leveling kits" for 97-03 F-150 4x4's are aftermarket torsion bar adjustment keys. They are indexed different and allow you to put even more preload on your torsion bars. In effect, they do the same thing you can do with your stock adjustments, on more. Stay away from them. They allow you to put way, way too much preload on your torsion bars.
