Doesn't matter if you have drop hangers or not. You will strip the front hangers. KP 4 link comes with front mounts to fit the stock holes. So, unless you messed with the front holes on the hangers, you're ok.Chris99GMC said:I have no idea how your setup is now, but the KP kit is a direct bolt-on to a 'stock' truck. If you haven't modified the hangers or stock leaf spring brackets you should be alright.
