I did the re-arched and add-a-leaf thing too. It lasted for a few years. Then I went with the new $500 custom Alcan springs and they were too stiff and too high. I removed 2 leaves from each of the Alcan leaf packs and added the air shocks and I'm perfect. If I load up the back with stuff I'm good at about 80-90 psi in the shocks. If I'm empty in the bed 30 to 40 psi is great. It gives you great flexability for load leveling. <img src="/forums/images/graemlins/smile.gif" alt="" /> I'm very happy with them.
