Shocks just control the ride, stiff soft etc. Springs can sack out and allow the drop along with bushings as stated above. I just did rear bushings urethane, and love them. Put a** end back up a inch and ride quality much better but not to stiff. About to do front urethane to do the same for front. It may put it up 1 inch at best as like above my bushings are shot. Longer springs can move up the front but again be careful as it may mess up steering geometry and ,make it tough to keep camber and alignment right. Stiffer springs will not sag as much as stock once truck is setting on it with full weight but will stiffen the ride some. Not sure if springs from 4wd will fit but I am sure they are stiffer and would not allow truck to sag as much. Just do all the homework you can so that you do not misalign any suspension stuff or adversely mess up geometry. Maybe go to junk yard and check spring swap from 2wd to 4wd. Maybe contact a local truck outfitter for more info and tips.
