Threw a Readylift Stage 2 2.5" leveling kit on yesterday and 285/75-18 Toyo M/T's installed today. Tires are equivalent to a 35x11.50. Alignment was still spot on (had to adjust the toe to get the wheel centered again). I almost opted for weights on the inside of the wheel only, but they were pretty far off and I'd rather have them balanced correctly than "this was as close as we could get". Pics below...
Leveling kit installed:
Not much to the kit, some spacers, shock extenders, new bracket for the brake line, a track bar bracket, and bump stop spacers (not everything pictured):
