2022 Jeep Wrangler 392
Hey everyone! First time here. Question for everyone who ordered their 392. Back in Oct 2021, I placed my order for my 392. I had a print out of my build sheet with a VIN about 2 days after my order. It seemed like a lifetime waiting for this beautiful Jeep. It finally came in June 24th. As I’m looking at it and looking at the window sticker, this we’re missing or changed. One being the gear ratio. I selected the 4.56 and it came with the 3.73. Does anyone know why this would have changed? It was also missing the trail camera. I’m assuming the missing trail camera was due to inventory or lack of parts.
When I recently built a “mock” 2022, the 4.56 isn’t an option anymore but is for a 2023.
Everything else is fantastic! Love the recon package, power, ride, sound…..
Any thoughts on this?
Thanks so much!

Heya Lindz! Welcome to the forum!

Someone correct me if I'm wrong, but window stickers always show the 3.73 in the first column, even if they actually have the 4.56 gearing that comes with the Xtreme Recon package.

Here's an example from a 392XR that I looked at in person:

Hope that's helpful!

Hmmm….that’s interesting. Yep, ordered XR package. I’ll have to pull my window sticker out and post it. I appreciate the input.
Thanks for the quick response!

Take a look at the crypto stickers build sheet, it will show the 4.56 gears on there if you ordered the XR.

On another note, those with the XR package that went to 37s, any need to re-gear taller than 4.56? Did you lose any significant power when you went to 37s? About to order 37 inch nitto ridge grapplers, considering upping the gears to 4.88 or 5.13 while I’m at it but not sure if it’s needed.

@7.62x392 - I went from 3.73 to 4.56 when I put 37's on. I would say it works perfectly for me. The shift points are smooth and consistent. I have a buddy who went to 4.88 and he has no issues with 37's as well. YMMV!

Edit - Sorry...you were asking folks with XR package. I'll crawl back under my rock...

Thanks for the reply. It does say 4.56 on crypto stickers. So confusing. I guess it’s a situation of standard equipment being listed on the left side the window sticker and then upgraded equipment listed on the right?
This is the first time I ever ordered a Jeep (car in general). It was an emotional roller coaster just waiting the 9 months for it to come in. It’s also the most expensive vehicle I ever purchased! I find myself just starting at it in the driveway! LOL!
 
Exodus 4x4 has a good page with charts on re-gearing.

Their chart shows 4.56 to be sufficient all the way to 39s for a JL 6.4 w/ 8 speed. Prob worth considering 4.88s and other upgrades (axles) if you’re gonna do 39/40s and use it.

I'm looking at eventually swapping my 3.73 to 4.56. Would you mind crawling out from your rock and sharing a little more about your experience? I know @BenLandry also upgraded from 3.73 to 4.56.

  • How much was the 3.73 to 4.56 upgrade?
  • Also where did you end up going? I'm near by in Ohio.
  • It looks like the TAZER JL Mini has the ability to change tire size and gear ratio in the computer. I'm guessing that's all that's needed from the computer/transmission/spedo point of view?

I think I would like to keep it OEM with a set of Spicer Dana 44 AdvanTEK 4.56. Honestly about the only thing I wanted from the XR package was the gear ratio, and maybe the extra fender flares to help keep the dirt spray down.

Thanks.... I'll now join you under that rock.

I dont think this has been said and I see you are a new member so I will point out that there is no way to simply select 4.56 gears, the only way to get 4.56 is with the Extreme Recon package and everything else that comes with it. The sticker will show standard features but then list options and will indicate 4.56 there under the XR package if selected.

As far as what you see as available on the Jeep website, it is irrelevant. You cant order from that site so what they say is available or not means nothing. Only things that is real is what your dealer can order from you from their system. When I ordered my 392 Granite was not a color available on the Jeep website but the dealer was able to order it.

To bad you did not get the camera. I find it useful and is apparently a paint to install one after purchase. I believe Z automotive, the maker of the Tazer mini also sells a front camera.

  • It looks like the TAZER JL Mini has the ability to change tire size and gear ratio in the computer. I'm guessing that's all that's needed from the computer/transmission/spedo point of view?
Yes, the tazer will let you select proper gear ratio and tire size if you change them. That fixes the speedometer and apparently the automatic trans shift points.

@Turboencabulator - I went with the Dana Nitro Ring and Pinion Kit's for front and back - $1032. A shop, literally, down the hill from my house (I'm in Indiana near Louisville) did the work. They did a great job! They charged me ~$1000 for labor. Yes...the Tazer will allow you to adjust for diff. gears. As you're aware, a fairly simple procedure to do that.

Now...here's a 🍺! Have a seat!
 
@Lindz392 the reason you cannot add 4.56 gears (which as others have mentioned are part of the XR package only) on the 2022's on the Jeep site is because haalfway through the production run of 22's the Xtreme Recon package was pulled and the website was corrected accordingly. You are able to order the Xtreme Recon on 23's, hence the gearing is available on the Jeep build site.

Does the tailgate spec tag prove it's an XR if it shows 35" tires?

No. I have a regular 392 I ordered in April and received in July. My tailgate spec tag says 35" tires which I don't have.

Does yours have the fox shocks all the way around?
