not all bars are created equal... some require more preloading (cranking) then others to be even from side to side. It is also possible they one that is maxed out was not indexed correctly at the factory.. if you are worried, you can reindex them, But I would hold off untill you need to.. like the front is sagging more then you approve of, or you do a lift, or add a bumper / winch... then you will need more cranking room, and you HAVE to reindex (sence you are already maxed)..
