My daughter has a 2012 2 door JK and wants about a 2" lift for it. This Jeep is a pavement princess and will not be seeing any off road duty. I don't have a lot of advice for her as my Jeep knowledge ends with the CJ and leaf springs. Are these "leveling kits" worth having? What does a 2" lift do to the steering and driveshaft geometry on these things? Any other issues such as brake lines or other linkage concerns?
