If that is the case, you will likely get most of the lift that you need from the All-Pro springs and hangers. You *may* run into some rubbing issues at the back of the front wheelwell, but you can pound the fender seam flat and even cut some of the sheetmetal if necessary. If I were you I would run the springs and hanger that you have, add a 1" body lift from Roger Brown, and then trim anything that rubs when the time comes. That is basically the setup that I have with 37s. The 1" body lift will allow you to raise the drivetrain and make mounting sliders easier without the problems associated with higher body lifts (bumper and shifter relocation, fan shrouds, ect).
