It's a 2015 JKU Unlimited with the auto 3.6L running 3.21 gears with a 3" suspension lift. Most driving what I do is 40-50 miles highway/interstate per day. I don't do a whole lot of offroading, whether that be rock climbing or overland, but now that my job hours have lightened up I'm hoping to get out more. Looking to have a good cross between the highway/daily driver, the power to tow something if i want, and to be capable offroad as well. I know I'm not driving anything super fast and agile, but I also don't want to be as sluggish as I am now.

 

Another item to keep in mind that will increase the cost is you will need new carriers for the gears. What I would recommend before dropping the coin on gears and labor is find local Jeepers with 4.56, 4.88 and 5.13's and take a ride to see what you like. That way you are only paying once.

I had my 2011 regeared to 5.13's because I knew my next set of tires will be 37's and only wanted to pay for gears and labor once.

I had 3.21's, 33's, and a 2.5" lift on my auto 2012 JKU . It was an absolute dog going uphill.

I'm now on 4.88's, 37's, and running front & back Truetracs. I can spin my tires and never have worries about hills anymore. Best regear decision I've made.

 

You didn't specify whether or not you had an auto or standard, but this chart will kind of pinpoint where you are, and will be.

 

I have a 2012 auto jku with 321's, and 35 inch Goodyear Wrangler duratracs and aev procal. My rig is a daily driver, and in my opinion it runs just fine.

Although I do live in Rhode Island at sea level, and haven't driven it up in the mountains yet. Also I tend to drive like a grandma. So your mileage may vary.

I had the same questions and concerns as you did, so I was hoping for the best but preparing for the worst, if it was really bad I would have regeared if I thought it necessary.

Another consideration is cost, in your local area how much is a regear job? I have seen some guys on the West Coast say they are a local guy charges $1,000 out the door front and rear with parts and labor, if I could find anything close to that locally I would absolutely go ahead and do it. But I have called several shops and stop in at quite a few and it ranges from $2500 - $3000 locally, in my opinion it wouldn't be worth it.

 

forget it.
if any one have it he must re gear it even with stock tire 245

 

I guess its all relative. I stepped up from a 4cyl tj with 31s and id bet if my 2015 had 40s on it with the 373 gears it has it would run circles around that tj!

 

As of now I want to re-gear either way. Running 3.21 with 33's is decent, but the highway/interstate I do could be better. Thinking of keeping my 33's but still re-gearing to 4.10's. Then if I decide to later I still have gears for 35's.

 

That's the way to go. Always leave yourself room to grow!
