need a leveling kit
You don't need a leveling kit because your ride height is adjustable. All you have to do is increase the preload on your torsion bars and get an alignment. You can probably gain 1.5 to 2 inches of lift.
The leveling kits for 97-03 F-150 4x4's are just re-indexed torsion bar adjustment keys. They allow you to put more preload on your torsion bars than the OEM adjustment keys. This will cause severe CV and ball joint angles which leads to premature wear.
Just crank up your torsion bars with the stock adjustment keys. Don't forget to get an alignment when you are finished.
