Gearing help

What is optimal gearing for 2013 JKU Sahara with 35s? Would lift/ no lift make a difference? Not really offloading or towing. Thinking 4.56 and being advised that way by shop. Thoughts appreciated.

6 Spd manual, if it matters.

6-speed is geared deeper in every single gear except OD. So honestly I think 4.56 might be a little overkill. 4.10 would be the sweet spot I think.

I agree with WXman with the 6 speed and 35's 4.56 might be a little deep. One of my old customers in MD is running 37's on 4.10's with an auto and it's just about right. If you are thinking of going to 37's down the road you may want to go 4.56's.

I have 2012 JKU AUTO with 35". Currently stock 3.21 and going to 4.88 in a week and a half. From the "gearing chart" and discussions with shops and here on forums, we decided that 4.88 would be the best spot.

now am reading differently.

It's all personal preference. I respectfully disagree with Teraflex that 4.10 with 37's and an auto is just about right.

If I was an auto on a 3.6L I would go 4.88 too with 37's and have a little oomph. 4.56 is probably "perfect" but want the little extra get up and go. IMO if you are going aftermarket go 4.56 or 4.88. You are pretty much stuck that way anyway, no aftermarket is tooling 4.10 and IF you do find some they will be more expensive than 4.56.

Im in a 2 door 35s with 4.88s in Florida. Perfect, even for towing here. If I lived where u do, and had a JKU, I would absolutely get a 4.88, or even a 5.13 if u tow.
Btw, mine feels a bit spunkier than stock with my set up.

You are a 3.8L so the deeper the better but on 3.6L 5.13 will be real deep.

Remember where he is is sea level and a little less mountainous then where we are. If the person was from Utah I would say 4.56 if you want to try to save a little on gas mileage but 4.88 other wise. This is for 37's.
