If your going to spend that much money why not go with 4.88 I went with them and there great.
My commute to work is 30 min on the high way and I'm doing about 2300-2500 rpm the Eco light is always on, and I'm getting 17.5-18mpg hand calculated.
The 4.88 goes up inclines like nothing plus it'll give me room to grow to bigger tires in the future.

kh202....4.88 is the worst advice ever.
I have a 2012 Auto Unlimited with front bumper, winch, and 35" KM2s. I put my deposit down and am regearing next week to 4.10s. Its the perfect gear for 35s and mixed wheeling and hwy. They cost more as they only come from Dana.
My buddy has the exact setup I'm going to run and he is at 2500 RPM at 70MPH.
4.56s will put you right at 2700 RPM at 70 and about 2900 RPM at 75.

Yea, MPG is not the best, I think I am around 14 average right now. I get better in my diesel truck on 35's. Or I just jump in the wife's VW diesel and get REALLY good MPG... but the JK is a lot cooler....
