I have a 2021 Rubicon Diesel JT. The standard equipment says it has the 4:1 Rock–Trac® Part–Time 4WD System. In the options, it doesn’t say anywhere that it’s been replaced since it has the Diesel engine, like it comments on the 3.73 gears instead of 4.10’s. The t-case no longer has an identification plate on it like my TJ did years ago.

Beings it is a Rubi, 4:1 transfer and 4.10 differentials.

You can go to https://www.mopar.com/jeep/en-us/sign-in.html and log-in if you've registered or register. Then you can check what your vehicle has per it's VIN.
With the diesel motor I know the axle ratio is 3.73. I went to the site as provided…thank you. It pretty much stated the same as the window sticker. For some reason I was just thinking the 4:1 transfer case was optioned out when you got the 3.0L diesel. I can’t remember where I saw it or why I thought it.

Sez it on the case right there "4:1"
I’m be…you can read Dr. hand writing. I’m guessing that last line is. 4 : 1

That's on me, I didn't pay attention it was a diesel. But the 4:1, swaybar disconnect, and lockers are part of the Rubi package.

Thanks for the feedback! Now I just have to deal with the oil leak found @ 450 miles on the odometer…lol
