I'm running 35's now but will go up to 37's with the new front axle. The springs are very long so they stay seated at full droop with 12" long shocks. That is something a lot of other springs don't do. It rides a little stiff now that I took the spare and bumper off the back. It rode great with the little extra weight back there.
I wish they made 2" springs for the 2-door. When I rotated the pinion up for the CV rear driveshaft I had to move the spring perches and as a result it sits up an inch or so higher in the back and looks a little funny.
