Jeep regearing

[CommieJohnnie]

Hello Jeepers! As you read this post, I am new to the community and got lot's of questions!! :)

Let's get to the point, I have a 2016 Jeep Wrangler Unlimited Sport. Bought it used (stock) brand new (2XXX miles) I got it modded up by DSI Customs. Right now the rig has 315R70/17 ProComp Xtreme MT2 with Rubicon Express 3.5" Lift. I am not sure if the Jeep has Tow package or not, assuming the least, it's got 3.21 gears.
I know this question has been asked many times here but for the sake of love, what gear size SHOULD I run? I do mostly town driving since I work 5 minutes from my house BUT I would LOVE to go wheel as often as I can! That includes Rock/Trails/Mud.
I don't hate the stock gears, it's just I do a bunch of readings about the 35s and 3.21 and it seems lack of power and tbch the jeep does feel sluggish ( I have steel front and rear bumpers and steel rock guard so it definitely weighs the Jeep down)

One last request, does anybody know/recommend a shop that does the regearing for under 1500$? I live by the Texas A&M Commerce University if that helps!! Thank you :-)

4.88 would be what I would run for your set-up.

As for a shop doing an install at that price, you might be able to find one. I'm not familiar with any that far east.

If you have any intentions of offloading, wait on regear and save up until you can add lockers to the budget and pay the labor once. Don't base your gear setup shop on price alone. ...again...pay once...

With your Jeep and tire size 4.56 gears would be perfect for driving around town and going off road. I would recommend 4.88 if your plan on going up to a 37" tire. Seeing that you have 3.21 gears the front carrier will have to be replaced when you re-gear the Jeep. You will also need to have a programmer to tell the Jeep what gear set that you have in so that it won't go into limp mode when you leave the shop. There are a lot of shops in the DFW area that can do the gear job that is in your price range but the programmer may put you just over budget. I know that I can do the gear job for your price range, but you would have to come all the way to Weatherford. If you have any questions fell free to ask.

And to answer your price question, gears can be done for $1500 including parts and labor. Check out Smith Offroad if you?re in Dallas. And like everyone else has said, wait until you can get lockers too. That?s what I did and it was well worth it.

Your gear ratio is going to vary slightly depending on which transmission you have also. Not apples to apples for your rig (mine was an '08 manual), but I found that 35s on 4.88 was less than ideal and ended up bumping to the 37s earlier than I wanted. My current setup is a 2015 auto with 37s and 5.13s. I can't go much above 70 mph and I don't get on any highways with it, but I planned that going into this setup. I would second Smith Offroad as a place to get gears done, they did one of my axles and I've been quite rough on it with no issues, but there are multiple quality shops in the greater DFW area so you should be able to find one close to you. I'll add my vote to both doing lockers at the same time and not going by price alone when making your shop selection too.

I ran mine on 35's with 4.10's for the first 5 years I've had it. It's a 2012 with the automatic. I never really noticed it being a huge drop n power with the 35's from the factory tires. Then a few months ago, I had Baertrax do my gears and went to 4.88's since I'm planning on going to 37's with my next set of tires. Holy cow what a difference it made. The Jeep really came alive with the 4.88's. I wish I had done it a long time ago!

I've been running 35's with the 4.10s also. Now you have me thinking. New tires aren't to far away from being needed and I will go with 37s.

What did you do locker wise when you did your gears?

[CommieJohnnie]

Thank you everyone, you guys are super helpful, oh and that chart definitely helps, I will check out Smith Offroad, but for now, I am leaning towards 4.88 because I will put 37s on eventually whenever the wallet allows Also, If I were to get the jeep regeared to 4.88 now with the tires that I have, would that mean my RPM will go up and mpg will go way down due to it being in a higher rpm than what it usually runs? (Sorry for terrible english I am not native) right now the jeep gets 15mpg. Lockers are a must, but what lockers should you guys recommend for a DD/WW?

[Bearkat]

I would suggest selectable type lockers. ARB air lockers is what I put at the top of my list.

You'll see an approximately 1000 rpm increase. It could mean an increase or a decrease in mpg or even minimal net change. All depends on how much city, how much hwy, and how heavy your right foot is.

I'm still running the factory Rubicon lockers. No changes, still work great!

I believe your current tire size is close to 35's. I would bet you would see an increase in MPG simply because you will be back to driving more into the power band than now. I thought my mileage would drop since I was gearing for 37's and would be running 35's a bit longer and thus at a bit higher RPM's. It didn't happen though and I get about 1.75mpg better than I did before the regear.
