So I have already purchased a set of front and rear Bilstein 5100s and pair of Mevotech UCAs. I just realized after doing more research, that the rear Bilsteins alone will not lift the rear. So my research has revealed that everyone on here recommends a 1.5" rear spacer as the largest on the stock rear shocks but what about on rear Bilsteins? Is it safe to go to a 2"? I plan to set the fronts at 2.8" and I want to keep a little rake so the truck wont look like its sagging if I have weight in the bed.
