So my XJ has about 2" of lift. I am going to either straighten and move my front brake lines, or replace them with GM 1/2 ton 2WD truck lines. I haven't decided yet.

My question is, do I need to replace the rear line for 2"?

I have not had a chance yet to find a spot to flex it out to see what it is looking like. I'm going out for the first trail trip with it next week and I want to make sure I don't tear any brake lines off!
