I would say that the easiest way to lift it would be coil spacers. With a body lift, you are going to encounter issues with your shifters, and I ended up having to rig myself up a new center console, and modify the hole in the floor for the t-case lever. To fit 31's with just a 2'' lift though, you may have to do a bit of trimming. I ran my 31x 9.50's on 15x7 rims for a couple of months with just a 2'' b/l, and the only thing i did was hammer the firewall a bit.
