I have a 6-speed 08 2dr JK Rubicon, 4" lift, heavy bumpers, winch, and gas cans. Sitting a little heavier than most other 2drs out there. I live in Phx AZ (1,000 elevation), but do a lot of wheeling up in the mountains around Prescott or Payson (5,000 elevation). I am planning on getting 37's and want to hear what gears y'all are running and how you like it in 2dr 6-speeds. I just got a bully dog tuner. I do A LOT of highway driving. So far I have read either 4.88 or 5.13. Gas mileage isnt a huge buster for me but would be a bonus. I dont do much rock crawling, mostly dirt trails and mud.
