To level most trucks to have to drop the rear to inches more than the front. If you take a look at my web site, I went with 2.5 spidals and 4' shackel/hanger. The truck is as close to level as you can get and keep some usability in the truck. I have trouble with the bump stops because I have not cut them. I plan on doing it sometime but I will probably won't need to with the addition of some custom made traction bars.
