I've read hundreds of post on here about lift kits, but can't find the answer. I'm going to lift my 84 CJ7 with a black diamond 3" lift. I notice that there is no transfer case lowering kit and no drop pitman arm with the package. Do I need to pick these items up separately or are they not needed for the 3 in. lift? Also, is anybody running 33's under this lift? I want my COG as low as I can get it, just wondering.
