Query: 35s on 2023 Rubicon 4xe

[kuldeepfarwaha]

Hi Experts,

I wrote a post earlier to seek advice on putting 37s on on my 2023 Rubicon 4xe. I reached out to shop for quote and it was kind of surprising. I am new to Jeep family so I felt like half of parts getting changed in my new Jeep to get 37s and it will cost me 20,000 CAD. (attached quote as picture)

Not really up to spending another 20K on top of 96k Jeep out of dealership, so I am thinking to go for 35s instead of 37s.

I reached out to shop again to check, He mentioned as below

"Yes if doing 35s on a Rubicon you can get away without the lift and gears for now.

Ideally 4.56 would be best suited for 35s but wouldn't affect as much if doing 37s."

Kindly share your experiences or guide me to right track please.

All I want is to get a beefy look on my Jeep by changing Stock Tires.

Looking forward for your genuine suggestions, thanks in advance.

Really depends on how you plan to use your Jeep in off-road conditions. Being a Rubicon, you don’t have to do the lift for 35” tire unless you off-road significant time in moderate and higher conditions. Definitely need wheels with different backspacing. If you primarily do on road and occasionally light-moderate trails, you can get by with wheels and 35” tires. May also want to consider a small spacer lift. I wouldn’t advise regearing yet until you drive it afterwards and see how you like it, especially on highway and up grades.

I am running 37" BFG A/T w/ 2.5" Metalcloak on my 4xe without re-gearing and I hardly notice. I do have less get up and go, but no trouble towing or hitting 8th gear. I have no plans to re-gear even after the TSB allowing it.

Hi RicRecon,

Thank you for insight. My 99% drive is going to be On-Road/Highways only. I have no plans to take it on off-road or trails for another year or so.

So, as per your experience, I shouldn't go for re-gear and just go for wheel upgrades.

what kind of experience you got after 37s without regarding, performance degradation or some other mechanical changes?

I really do not want to have performance changes or mechanical damage which will make me spend more in the long run.

Kindly suggest..

Based on this use case with no offroading do not install a lift at this time, you will have performance changes, no way around that. Best option I would suggest is keep the 33s for a while. Hit some trails. Find out where you feel your Jeep has defencies based on the trails you like to do. Only after that make a decision to go bigger.

Don't settle for 35s, you'll just wish you got 37s.

You don't need to regear a Rubicon 4xe for 37s. Even on 3.73s of the Sahara we have tons of power on 37s, so your 4.10s will be way more than adequate.

Also seems like they're hitting you for a hell of a lot for tires and wheels, you don't need the new tpms they can just use the ones you have, you don't need the new steering stabilizer, rock jock parts, or 3.5 lift for 37s either.

For your use case just get a 2" spacer kit, some adjustable upper or lower front control arms (to correct caster) and a new front track bar to center the axle. The rest of the stuff are great parts, but completely unnecessary for your use case.

There's really no reason you need fork over $20k to do ALL of this work all at once.

And there's no reason at all to buy $325 worth of TPMS sensors when you can just reuse the ones from your stock wheels.

For 35's, you could really just buy new wheels and tires, and be done. Only costs the price of the wheels and tires and install, less than $5k.

For 37's, you could just buy wheels and tires and a 2" spacer lift and front driveshaft (which was curiously not included on your quote, but you do need one), and be done for under $6k.

Or if you really want a full blown lift kit with all new suspension parts, then you're still only looking at $10k all in.

All the other upgrades they listed are great and all, but really not needed. Especially this early in the game.

Why spend like $7k upgrading the steering, before you even know if it needs it? I'm running 37's and my stock steering is totally fine.

Also $3500 for axle regearing is totally unnecessary for 35" or 37" tires. It can be a nice upgrade, sure, but it's hardly a requirement.

Thank You for your input, that's what I was thinking why 20K ? After reading all your feedback, seems like guy was just loading the quote with all the pricy items.

I am very close to Buffalo (NY), moving to Niagara Falls (Canada). Any recommendations for a genuine guy nearby in US who is reliable ?

I mean he was giving you a built jeep ready to go tackle extremely difficult trails at Moab. The labor rates weren't bad at all (the regear price was at least a grand high though), but just massive overkill in terms of what was being put on.

Honestly I'd look up the parts yourself and just tell him these are the things you want, and see where he comes in. For spacer lift I'd just go teraflex 2.5 inch performance with shock extensions (about 450-500 bucks), front control arm drop brackets (pick your brand such as AEV, metal cloak, teraflex), and an adjustable front track bar (again pick your brand)

Edit: I'll state that the spacer lift and drop brackets are more than adequate for your use case both now and future as stated. Obviously if you suddenly become a real hardcore rock crawler these aren't what you're looking for, but they're also cheap enough to not hurt too much if replaced.

My advice: don't change anything. Just drive your Jeep for a while.

33" tires are already bigger than many folks really expect or realize, and the Rubicon is quite capable out-of-the-box.

Yes, there exist trails for which the stock suspension and tires are not adequate. It's also true that such trails can be quite frightening, and many folks turn out not to enjoy driving them after all.

Get out into the sticks. Use your Jeep. Then decide what, if anything, you need.

Thank you for your suggestion. Only triggering point for me is to give a beefy look on my Jeep, I do not plan to go out to trail or off-roading.
So, that's the whole story behind.

I get activated by looking at social media posts, how well guys modify their Jeeps with 37s or 40s with new wheels, I am looking for :

Sounds like you forgot to take off your rolex when you walked in to ask for the quote.

If your serious about not off roading, and your gonna pay for the work to be done anyway, I'd actually consider just doing the Mopar 2", throw on the 37" wheels/tires, and be done with it.

You could go cheaper on the lift, but that will get you a decent setup, and then you know you're covered by the warranty and won't have to screw with any shops bending you over down the road (or at least bending you over further than the dealer.)

EDIT: Note, the 4xe mopar lifts tend to get less than advertised on a Rubicon. But for tire fitment, you're really just looking for added bump.
