I agree. I did 4.88 on my 13 jkur auto on 37". I won't do it again. My mpg dropped 2 mph and I could barely tell a difference. 2900 rpm at 75 was a waste of gas. Just my experience.

No grief was given. I was just asking you to expand on what you didn't like about it. Figured it would be more useful to the OP than just saying you didn't like it. Opinions are the basis of the forum, they're just not useful if they are not supported by why someone takes a particular view.

Yeah but engines don't typically "love" running at higher rpms. You may get your power a little easier but the higher the rpm the higher stuff is moving,more heat. Etc. Fuel economy won't go up.

I have a post in here that shows a picture of me doing 70. I asked a specific gear question with what everyone was running when I was considering gears.

2014 2dr auto
4.56 gears
35x12.5-15 KM2's (measure closer to 34)
@ 70 I am about 2800 RPM's.

That shows 2700, but useful to see. Any chance you can toss a GPS in a similar picture to show that your speedo is actually correct?

It's correct. My GPS is in my phone which is also my camera. Was the first thing I checked when done.
