for Dodgefan, adding new coils might give more lift than he's looking for (having a 2wd). the pucks and shackles will lift the truck precisely 2" higher than it currently is. adding 2" lift coils will lift the front up 3" above what it is now (2wds are shorter than 4wds).
and yes, going 2" can help keep costs at bay. just need pucks and shackles. But we of course can't guarantee you won't find issues along the way. :(
