I have a 1991 chevy s10 and was planning on putting a 2" body lift and a 2" suspension lift on it. Would I run into any internal problems by doing this? For example maybe I would need to extend the fuel line.
The fuel line should be fine since it is attached to the body. The brake lines may be a problem because the extend from the body to each axle. You may also have to extend some ground straps to the frame. Honestly, 2" shouldn't cause too much of a problem.
