^^^ This is about right.It depends on how much travel your willing to lose. You can not lift your jeep and use huge bump stops and get away with 37s. But that would make your jeep pretty much unusable.
my mate runs 37's on a 2dr with a 2" lift and flat flares/fenders..
correctly bump stopped with 27/28" shocks, his rig works well.. 30% up travel, 70% down travel
