I am loking for more articulation for my 40, and am looking for something bolt on. right now it has a reverse shackle lifht that gives it 2-3" fitting 35s. I am not looking for any more height, and dont want something that will mess up the steering geometry because it already has an aftermarket steering pump with the dropped pitman arm and such. I am not looking to be hard core but want a little more then it already is.
