hey guys i have a 2011 JKU auto with 35's AEM CAI and I am getting read to order my gears and a procal. just need to know what size to get. a lot of he charts say 5.13 for auto, is that what i should get?
thanks

 

5.13, hands down. I had a simpler setup and I had stock 4.10's, 4th gear was absolutely useless and that's here in Florida.

 

I agree, I have 35's with 5.13's and its great, and I went with the flashpaq and adjusted for everything I have and it works wonders.. I wanna set the auto shift points, just not sure really how or where to set the at...

 

5.13 is the way to go for auto. I got manual and slapped 4.88s in last week. Performance is back to stock. And on board computer says I'm getting anywhere between 18 and 20 highway
And staying pretty steady at 17.# city. I'm back and forth between pennsy and New York. And the 17 is with NYC traffic.
Quick piece of advice if you have elockers...
Make sure whoever installs it makes sure the switch for the locker in the rear is on the correct side of the dog clutch. Believe me it will save you a second trip and having the rear lockers engaged when they aren't supposed to be.... Rubicon rear ends can be a bitch to work on if never done before. There are a few threads on this.

 

Like they're all saying 5.13's perfect for your set up ...... Enjoy

 

hey guys, thanks for all the help. this is really going to make my decission easier. cant wait to get it done, just got to get back home from afghanistan to get it worked on. and again thanks
