There is enough brake line, from factory, to facilitate a 4" suspension lift, at full articulation. Meaning, with no sway bar connected. In some extreme cases of flex, I did manage to get the brake line tight, so I did put some longer ones on. If you ever have any doubt, just pull up on a rock, with one tire, until the other side starts to come off the ground. That is your maximum amount of flex. Then get out, and see what your brake lines look like.
