On a basic TJ build around 35s with a ~4" spring lift and a small body lift and intact body, what amounts of travel can one reasonably expect to see after a thoughtful selection of shocks and bump stop extension?
I think you could easily put 10" on, maybe even 11". Rework the lower mount (no welding or scary cutting) if you want to increase or decrease up/down travel. IMO you could do that with 2" or less bumpstop up front, and maybe 3.5" in the rear.
