I have 4.56 gears with 35's and a 6 speed manual and Pentastar. It's great for driving around and for moderate trail riding. But since my Jeep is a Sport it has the 2.72 low range Tcase. I can't crawl very well because I don't have a low enough low range. When I'm on a ledge I either stall or give it too much gas and lose traction. A Rubicon case would make a huge difference. But even around here they're hard to find. I may end up going with an Atlas instead.
