I have a 2dr. Rubicon Auto
It had 4.10's and I am running 35's ( did ok until I tried driving up a grade ) It will run fine just gutless heading up inclines, and dont forget the overheating transmission " DING ". My rig is my everyday driver and I can tell you that I drove with the overdrive off everywhere!
Just regeared to 5.13's and could not be happier! I no longer have to keep my foot agressive in the pedal at freeway speeds...
I would say with an auto go with the 5.13's

I have an X with 3.21 gears and just 33 inch tires, manual. I notice the difference but it isnt that bad. It may feel different with an auto because with my manual I decide when you change gears. With only my experience with my jeep my guess is that I would be happy with the rubi 4.10 gears and 35's, and it would be a toss up whether I liked the 3.73 shahara gears with 35's. But without trying it I would never know for sure.
So get everything on first and have the money ready in case you hate the gearing. If it drives like a dog in your opinion then go get your gears. If it isnt bad then spend the money on other mods!

I still don't have a Jeep, but I'm getting closer and closer every day. The other thing I do every day is I read this site like it were the Bible. I am trying to decide on just the right mods that will give me the most bang for the buck and be the most aesthetically pleasing to my eye. Though I do find some great info and great write ups, I also have found some conflicting info (imagine that on a forum).
Today's subject of confusion is : RE-GEARING
I will either buy a Sahara or Rubicon 4-door , auto. Ideally, I think 35" tires look best. A jeep just looks right sitting atop that much rubber. I'm no hard-core off roader, but I like to have the option. As such,, I won't need racing coilovers or Mud Grappler tires or a $3000 lift. But then again, need is subjective.
Here is the question at hand:
If I buy the Rubicon (with 4:10 gears), will I HAVE to regear for 35" tires? What is the worst case scenario if I don't?
If I buy the Sahara, I am going to assume that 33's would be as large as I should go without a regear, but is that even true?
I have heard people on here say you can run 4:10's and 35"s together with no problems, and then on another thread, someone else says the opposite.
Who here would like to write the definitive dissertation on the regearing situation?
Also, I'll give you some particulars about the equipment I am leaning toward and you can tell me if I am on the right track, or not.
I'd prefer the Rubicon---not sure why, I'm just leaning that way. I will get 17" wheels with about 4.5" backspacing, a 2.5"-3" lift (maybe OME) and I'm thinking about 35" BFG AT. I know what you're thinking---those are not nearly aggressive enough for a lifted Rubicon. I agree, but it's a daily driver and you guys have me just about scared away from mud tires.
So with that equipment in mind, would I really need to re-gear?

Wow. I dont know anything about any of this.
Dana 44 rear with Anitspin differential axle
3.73 axle ratio with tow package
Dana 30 front
36 inch tires
Not sure if I need to do anything to my JK or not.
I have had no troubles, except at high speeds on the interstate, when it sometimes seems the power isnt there.
i havent had any difficulties taking off from a stop, or climbing.
any help would be appreciated.
