Hi folks, Im in Raleigh, NC and just bought a 2012 Jeep with only 9000 miles, 4in lift sitting on 315/75/16 Goodyear's. I am officially in love and can't wait to get out on the trails. I do have some concerns though, I have been told that I need to upgrade some parts on my jeep due to the lift by a few different people and then other people told me that my jeep is just fine and that the 2012's basically came ready to roll. Any recommendations?
