Lockers are always a good decision! Just dont run them when you really dont need them. Nothing buries you up to you axles faster in sand than locking box axles and flooring it.
I went with 5.38 gears and man that is one of the best things ive ever done!

|HeavySmoke||Are lockers dumb idea on daily drivers|

What I learned from them is that the gear ratio is one of the inputs into the safety systems and it could impact how ESC reacts should it need to. For this reason you should (according to who I spoke with at AEV) set the ratio regardless if you have a manual or an auto. Just an FYI for those who may wonder like myself.

If you look at the gear chart, the 2011 models actually came from the factory with the wrong tire size. A 29" tire is the largest tire feasible (yellow) and 30" was off the chart too big. The 29" with 3.21 and a 3.8 is equivalent to a 35" with 3.21 and a 3.6. WOW!
Also, I live at low elevation, drive over 80 mph routinely, and do light trails. I'm doubtful I ever regear.

|Jeep757||from a 30" to a 33" i did i could tell a difference in some power loss and definite drop in mpg with 3.21's. per the math i only need to go up to a 3.73. per the chart, 3.73 is the minimum(yellow) gear required for that tire size. 4.10 is green (idle, good for DD even up to a 35") and 4.56 would be blue(performance, fair for DD) for 33" and green for 35" for the 3.8L/Manual|

|rubisteph||Mostly math yes.... but get it right.... the formula is simple... new tire height/ old tire height X actual gear ratio and this gives you the ratio you should get to run along the same rpms..... add to that the added unsprung weight and rolling resistance and go one size gear lower to compensate... therefore a 35'' tire/ 32''tire X 3.21= 3.51..... I think one size lower would be 3.73 in a dana 44.......|

|ave8er||If you were ok with the 3.21 gears on your stock rig you should go to 4.10 for 35's and to 4.88 for 37's. Or go to 4.56 which will be fine with either. This all hinges on your being ok with 3.21's to start with..|

3.21 should go up to 4.56 for 35s
That's mostly math.
At 3.73 and 35 things get more subjective due to cost and ROI. I would regear since I would be adding other weight and perhaps towing. I also value a slow crawl.
Its not a slam dunk like it was a few years back due to the changes in the model.
At 4.10 and 35, the ROI is so low to go down to 4.56 unless you are cracking pumpkins for lockers or doing other serious work anyway.
So its objective to a point, then subjective or situational. (Gear charts don't lie but they also don't know what you are doing, what you like or if you run heavy. That's why they have the color bands for marginal, average and performance)

I have read the entire thread, and there is no real consensus amongst all of you. It appears it varies with each individual who have upgraded tires aka. 305,315,325 etc specifically on the new 3.6L 4Door Wrangler.
I think majority of us are weekend warriors, and use our jeeps as a daily driver. Since the common size of tire upgrade are 35s, what would you all suggest to those who enjoy a bit of trail riding on the weekend, and a lot of weekly back and forth to work driving for gear upgrades on a 3.6L (2012-2014)
Some keep the stock 3.73, some upgrade from 3.21 to 4.10, 4.56 or 4.88. I understand that those who go up to 4.88 are usually on the fence with the idea of going to a 37 tire. I also have found that those who do a lot of towing go up to a 4.56.
In summation, if the average person looking to beef up their Jeep to 35s who uses it as a daily driver and hits the trails on a 3-4 time a month basis....what should he ought to be running. (Maximizing Fuel Efficiency/Reducing Wear/ Consistent Stock Ratio of RPMs).
For argument sake, lets say the elevation level (AMSL) is anywhere from 250' ft (highway/work driving) and trail riding at approx. 1,200ft.
Let's also assume that we have a 2.5-3" lift on the vehicle. From my research and observation it appears that 3" Lifts are probably most common for those with 35s.
Thank You in advance for your support!

My dealer has a 2014 auto 3.73 that they installed a Mopar stage 3 lift and 315/70/17 Duratracs. I took it for a spin (waiting for my 2014 on order) to see what the big deal was regarding gears. I don't currently drive a Wrangler on a daily basis, but I didn't notice any difference in acceleration between that vehicle and the original auto 3.21 that I drove. The 3.73 with the 315/70 Duratracs was just fine in stop-and-go traffic as well as on the interstate. The thing has more get-up-and-go than my current vehicle. Of course, this is more related to daily driving. I didn't test with towing or off-roading.
I think the only hard and fast rule to gearing is to try what you have. If you don't like it, then think about regearing. Some people seem to think that the vehicle won't move if you don't regear. It's all about what the driver can live with.

|BB1857||Sometimes the answers on these threads drive me nuts. This school of doing something right or don't do it at all is just wrong when it comes to gearing and 35s. Wranglers can be had with three different sets of ratios therefore there obviously isn't one "right way". If you live in a very flat area there may be no real need to regear. Will the Jeep downshift a bit more than if the gearing is higher, yes but it still doesn't mean you're wrong if you put 35s on and don't regear. I drove my Sport for two months with 35s and 3.21 gears in a very hilly area and while it wasn't ideal it's not like it wasn't driveable.|

|HeavySmoke||I have a 2012 with 305s they are 34" and plan to regear I think 456 will be perfect. Any thoughts|

But if you want to go with any kind of full case locker you want to do it when you do the gears. That makes the regear more expensive but it's cheaper than doing the gear work twice.

|ave8er||from 3.21 to 4.xx do both carriers have to be replaced or just the front?|
