Brake lines question

[calcrc]

Hello once again ! If I decide to do 3 inch+ upgrade suspension. I would need to upgrade the brake lines also I have been told. Is it hard to or very expensive to do ? I have no idea how to do this and would like to know what I need before going to the shop so that I have a better understanding.

Should be fine, once you go full LT in the rear extended brake lines are necessary.
Not particularly expensive or hard at all to swap lines, but you will need to bleed all four corners
