Diff gear 'kit' for 2023 JL Diesel

[rubiconman]

I would like to change from 3.73 to 4.10 on my 2023 JL diesel. Is there a quality 'kit' that I can purchase, any suggestions are much appreciated. I am currently running 35s. I have a set of 37s as well, but have not run them as much as the 35s. Thanks!

This if from my Jeep build sheet:
4:1 ROCK-TRAC HD PART TIME 4WD SYS
DANA M210 WIDE FRONT AXLE
DANA M220 WIDE REAR AXLE
FRT DIFF-ELEC LOCK W/AXLE DISCONNECT
E-LOCKER REAR AXLE

The shop that you find to do the change should be able to get everything together for you and provide a good warranty on the work.

You can try to install the gears yourself but I suggest you research what it takes to do it right. It's not hard. Just very meticulous work that requires special tools.

Finally, you'll probably find that going from 3.73 to 4.10 doesn't really buy you a lot. The ratios are so close, the juice isn't worth the squeeze. If you're going to bother to change, go to 4.56.

One alternative is to find some Rubicon axles with 4.10s and swap them in whole. Then sell your original axles to someone who wants to regear anyway.

Roger that.

I would still like to see if there are any package deals on the parts. How many people make the gears? Are there some to avoid?

Thanks!

Nobody has a "kit" that includes everything. I tend to buy my stuff from East Coast Gear Supply. They have pretty good customer service. And they can make sure you get everything you need in one shot.

As far as brand, I stick with Dana-Spicer when I can. Though for older axles, their value line (SVL) is lower quality and I look for better. Yukon is a second choice. I have heard second hand that Nitro isn't the best.

Realistically, there's only like 2 or 3 manufacturers in the world and all the brands buy from them and slap them in their box.

So I have my cart loaded up and ready to checkout. Just need a sanity check before hitting the buy button. All of the Dana Spicer parts (that I am about to buy) are listed as "Fits 2018+ Jeep Wrangler JL" then a little further down the description, each part says it is compatible with 2018-2022 Jeep Wrangle JLs ... mine is a 2023 model.

Don’t buy the gears if you don’t plan on installing them yourself.

The axles are the same for all JLs, 2018-2026+

The 2018 JK is different so make sure everything is for the JL.

Another critical thing to check. There are 2 front and 2 rear axles available. The front is the M186 (Dana 30) or M210 (Dana 44). The rear is the M200 (Dana 35) or M220 (Dana 44).

The parts are specific to each axle and only work in the axle they're for. There's no way to make them cross over to a different axle. At all.

Make sure you know which axles you have and get the right parts for them.

I second ECGS, Will’s customer service (919-672-2705 Ext 1011) was knowledgeable, excellent and timely. He sent them to Gear FX for finish, they sent them to me. (the install kit (Yukon) sent to me) BTW @rubiconman he said “we always recommend Dana for these”

Thanks for the details!

My 2023 JL definitely has the M210 and M220 axles.

These are the parts I am planning to go with:
FRONT:
SDH-10050939
SDH-10044799
SDH-10040469

REAR:
SDH-10067141
SDH-10040651
SDH-10040478
