Interesting chart. I have a 2011 Rubi Unlimited with auto, and 33" tires, and I have no performance problems at all, yet the chart suggests I should be running 4:88's instead of the 4:10's.

All of the gears are coming out of the same factories overseas, the different companies just package them in their own fancy boxes. Yukon probably has the best rep, but any should be fine.

The ones you are looking at are 'lockers', which will replace the stock carrier. Do you need a locker? If you do want a traction device up front, consider a $390 TruTrac instead of a $1000 selectable...

Yes and if you went to 5:13's your mileage would suck even worse but your power would be off the charts. It all economy of scales- you trade performance for mileage with the JK. What do you plan to do with your JK?

Auto, 5.13's, 33" tires = a bit over 2500rpm @ 70 mph. Not really screaming high rpm, is it? In fact, it's pretty much right where this engine likes to run, right? So he would hold OD better, with less lugging of the engine or constantly downshifting and adding another 1000 rpm. So his mpg's would actually improve, not suck even worse...
