We bought this 23 Diesel JT with 7,000 miles on it with a build based around 40" tires in mind. We bought the Sport S package because everything underneath was going in the trash anyway. We are sitting at Granite 2.5 right now (the ".5" part was the exhaust diet). Granite 3.0 will happen when I finally decide my departure angle mods just aren't going to cut it and I put the Motobilt bed on it or cut the bed down myself. Stay tuned.....
