I just saw this on the AEV Forum. I was wrong about the springs.

I guess I should have read the op better.
The PW does sit about 1.5" taller in the front and 1" in the rear.
The PW springs do have less load capacity in the front (FGAWR 4700 vs 5500)
In order to fit the AEV kit, the non-PW springs must be used to get the geometry correct. It was designed to be a 3" lift in the front, 2" in the rear over the non PW height. The 3" lift from the standard height as well as the way the kit moves the axle forward is plenty to run 37s. Its important that the front AND rear springs are swapped in order to have the proper frequencies (think the front end bouncing at one rate and the rear bouncing much faster...they need to be designed as a matched set!) The part numbers are in the instructions. No noticeable difference in articulation.
If you were to use the PW springs the steering would be off and frankly you just don't need that much lift. You do need the added capacity when running a bumper and winch and gear which is how we consider most AEV customers.
The ProCal will work to adjust tire size and gear ratio.
Currently there are no gears on the market for the new trucks other than 4.10 but we're working hard to change that. We should have 4.56 available soon and hopefully 4.88 which is what would be necessary for a gas truck to run the 40s.
