If the OP is looking for the least expensive way to gain some height then a new set of springs in a new lift kit isn't it. And if he says not a body lift then a body lift isn't it either. While I agree with both of you 100%, neither is what the OP is looking for. If it were me i would lean heavily to the body lift. He already has shocks and springs that he likes or he wouldn't specify wanting to keep them. I think suspension, steering, and brakes are the exact wrong thing to try and save money on, but hey, I'm not the one who will be driving it.
