I just lifted my ranger yesterday with a 3" spindle and 2" rear lift block...we ran into a problem where the brake line didn't go far enough when turning. So we in bolted the brake line from the frame and it just hangs a lil now but have full turning and everything. So I was wondering how important a new brake line kit would be or if it is fine as long as I keep inspecting them to make sure there is no leaking or binding?

I think you should be ok, but brakes is a major factor on your truck. I would get longer stainless lines especially if you have larger tires.

Yea brakes isn't something you can duct tape up.... Just get some stainless hose and make your own brake lines.... Super easy and cheap to do.
