I have fitted Bilstein 5100 rear shocks to this and the ride is perfect! If you take it to a general 4x4 shop and ask them to watch a few minutes of video I had to pick up my truck as they didn't put spacers on the front as the instructions don't say anything about spacers but my front did outside of alignment. was almost 2 inches lower than the stern. I was glad I had to go back as I saved $500 in labor compared to off road shops. Now I need to find wheels and 35s.
