Recommended JK Gear Ratios

I saw this chart online and I thought others might be interested in it. Looks like it applies to the 07-11 JK's.

The biggest thing we need to know is it a 12 or newer or older. The new motor makes a difference.

Well, I'm gonna say its older than a '12 since the chart says 3.8. 12 & 13 have the 3.6 right?

It was nice to meet you the other do and I hope you enjoy that bumper, and yes you need gearing bad, Im sure Jeremy has good info to fill you in on, I would say atleast 5.13

Hey! It was nice meeting you too. I definitely need the 5.13's. I just put the chart out because I thought others might like to see it. Let me know the next time you are headed over to Uwharrie and maybe we can meet up. I've already started pricing out the sleeve/gusset/axle additions. Thanks again for the bumper and I'll send you a pic when I get it installed.

With the 3.8 you can never have enough gear, 5.13's for 33-35 and up. The 3.6 is a totally different animal, you can run 33-34 on stock 4.10s with ease.
