Well from recent experience...I have a 2012 - 4 door - automatic...35" tires...added bumper weight...stock was 3.21 gears...Installed 4.88...
HUGE difference in city and highway...I will admit revs a little high on highway 70 MPH 3000-3100 RPM...
No problem passing or keeping up...Otherwise would not change anything...Mileage about the same that i see...
With other gears transmission was always down shifting - these gears stays consistent...This is just my experience with gears...
Installed Yukon - professionnaly installed no problems at all...

I went with a Rubicon knowing I'd use it off road. and with bigger tires.
the factory 4.10s on my 2012 auto work just fine with 35s
this thing is wicked quick. Sure it could be quicker, but I'm very happy w/it.

The chart is not accurate for RPMs. It's off by 250-300 RPMs on many gear ratios.
That can be a huge difference for people who commute daily at hwy speeds for both MPG and life of their power train.

We went with them because of cost, but several in our Jeep club used them as well. No one has had any issues. Not sure why they've gotten a negative rep.
