Taking off a 4inch lift

[2003powerstroke1]

I have a 4 inch suspension lift on my truck....i was wondering what it would take and how hard it would be to take it off and put on a leveling kit. any help would be great. I had 4 wheel parts put it on but they charge $500 to take it off and install a leveling kit but that doesnt include the price of the new shocks and leveling kit. So i wanted to do it myself.

Most likely you will need factory springs and a leveling pack for the front. The rear is probably just a block so you would need a factory block and maybe factory u-bolts. Also you will probably need a stock pitman arm. Would be best if you could find someone local that has a leveling kit and wants a 4" lift and just swap the parts over.
