Hiall new to the forum, seems like a nice source of info so here are a few questions i have . I just swapped my tricked out 03 350 w/ 150k miles for a stock 06 250 fx4 w/ 30k miles and am beginning the process of fixing it up. the prev. owner has put a leveling kit on it but the rear end is sagging. with nothing in it it apears that the back end needs to come up 2". Overall the truck is 2-3" lower than my 03. Is this a 250/350 thing? is there any way to raise the rear end with new shocks, or an ad a leaf? I would like to stiffen the rear because 2 weeks in i have already loaded it down to where it looks ridiculous. on my 03 i souped the engine, and added accessories but never did anything with the suspension so i figure i'll get the suspension done first on this one? any help or advice will be greatly appreciated.
