From personal experience what would you guys recommend for a '10 Unlimited that I am going to run 35's on and is going to be a DD with probably less than 10% offroading and it has an automatic?

 

You will hate to hear this but do a search there are tons of threads on this. With and auto you will want 5.13 and 4.88 with a manual.

 

Yeah I know, I just wanted to see if anyone had any personal advice that they were running. I've got a friend who has an auto and is running 4.88's and says that he likes it with 35's. 5.13's just sound super low, but what do I know?

 

If you cruise on the highway between 55-80 MPH, the 5.13 are a very nice match for the auto, the anemic 3.8L and mindless PCM.

If you want to know the reasons and how many run 5.13 vs other ratios just run a search on gears.

 

I guess I'm a idoit but I'll ask...what is the PCM you're refering to? Also what kind of mileage on the highway estimated are people getting with the auto, 5.13's and 35's just out of curiosity?

 

There is a ton of info on this site, (hundreds of gearing threads with all the pro/con opinions and advice you could want) and I find it humorous that so many people simply can't be bothered to look...

Here is a blurb from the faq's right at the top of this section:
And check the chart for rpm info for different gear/tire combo's (be sure to use actual tire heights, not mfg's listed heights)

I didn't say that I couldn't be bothered to look...I just asked for personal experience and that's it. I've read all the hundreds of threads and there is so much contradictory info on here that I was wanting to hear some personal experiences in what people were running. Thanks for you help though.

 

Cool...I appreciate all the info Planman!
