Hi Guys, Im planning on lifting the ZJ and purchased the rough country 3.5lift kit and im wondering about the front trac bar. their brand states 0-3.5in lift however if I get new isolators it says they add close to an inch so this being said will this trac bar be fully at its capable limits? and should I go with the 3-6 bar from somewhere else or the 4-6 bar from even somewhere else which im sure someone here has done and would this also require the same size in the rear.- thoughts?
