I looked at and even purchased one leveling kit and didn't like the way it looked. I did some research and found the Power Wagon has the Bilstein shock that is two inches longer and the right track bar to raise 2.5 inches since that is the height they sit at. However the Power Wagon springs are not nearly robust enough to support the cummins so I went with Sky Jacker 2.5 springs. All in all it came out good, had to index the left spring as they really should make a right and a left. I'll get it aligned int he morning to get the caster set back and the steering wheel back to center even though after the track bar install it's barely off.
