Re-gearing and around it

[CRIXU5]

Hi everybody. New to the Jeep scene and just picked up a JT Rubicon with a mopar lift with 35s. I’m upgrading to 37” tires. I’ve been told to also upgrade the gears which I just ordered 5.13 from Dana. Then I was told to add trusses since I’m already swapping gears out. I’m sure this is common and maybe gone over this a lot times. What my question is, is there anything else y’all would recommend beefing up since the axles are down and make labor easier? Thank you in advance.

Not sure what your application is but I am running 37s on stock 4.10 Rubicon gears and haven't done a thing to my axles. I do moderate off-roading and would like to upgrade to 4.88 at some point. So far nothing has broke but I'm not hardcore wheeling a Gladiator.

It really depends on what you intent to do with the Jeep. As you can see you're already on a slippery slope.

If your going 37's, you need to regear. If you are regearing, you should do lockers while you are in the diffs. After gears/lcokers, you might as well truss the axles while your at it. While you are trussing the axles, you should upgrade your steering. if you are upgrading steering anyways, you really should get new driveshafts. Now that your pushing your Jeep harder, you need to look at new axle shafts too. Now you've got $10-$15K in your axles and for a couple grand more you could have just bought a set of spicer 1-ton axles already geared, locked, and ready to go....

Honestly the factory set up on a gladiator can run 37's. Will it be a bit slower than a factory gladiator on 32's? Absolutely, but it's not going to kill the Jeep either. Unless you know you are going to tow heavy, or spend 95% of your times up in the Colorado mountains, Gears are nice to have but not absolutely necessary.

I'd run your setup exactly how you have it, learn the limits and short-comings of the truck, and wheel with a group of people so you can see how their mods benefit them. You'll learn more about yourself and your truck that way, and you will really understand WHY certain mods are useful and how to correctly use them. I've seen completely factory gladiators with nothing more than a set of all-terrain tires and some body protection get out of some crazy situations because the driver knew what they were doing.

He's got a Rubicon, so it's already locked on both end.
I'd skip 37s and go 38x13.5. If you have extra cash, upgrade the steering components, tie rod and drag link, maybe an adjustable steering stabilizer too. If you still have more cash laying around, throw in some rcv axles. You should be good for awhile. Maybe do the ball joint too. lol

I'm currently on 37s, probably going 38s in a couple of months. Will have to do tie rod and drag link after that. Just ordered a Falcon 2.2 SS. Gonna piece it together.

Before you take any advice on all the sh*t you could/should buy - what are you going to use the JT for? Let's start there...
