I put a 1.5inch Daystar Leveling kit on my pickup about a month ago. I had to replace the front shocks with stock 2500/3500 2WD shocks, which are about 2" longer. Some people will tell you that you dont need to get your alignment done. Im here to tell you that the steering feels really tight with out it, and the front tires are bowed inwards a little bit, so I would recommend it. BTW i have a 2008 Ram 1500 2wd, so it shouldnt be a difference.
