Dana 44 Axle Comparison

[Alchemist03]

Hello all,

I was looking through the 2023 ordering guide and noticed all these different axles. I currently own a 2019 JLUR and went in with the knowledge that I have dana 44s front and back. One the order guide there are D44 standard, D44 HD, etc etc. Were there upgrades to the axles at some point? Are these just different axles between the wrangler and the gladiator? Were there different axles being used in the XR packaged jeeps? I clearly have been living under a rock lol. Not that I pushed my jeep to its limits yet but just wanted to know.

As much as I love my Rubicon, I always wonder how I would've built it up had I gotten a Sport or Willys and got take off parts down the road. Also been hearing that the JL generation axles can handle way more than the JK gen and that its not common for people to be running 35s or even 37s on the D35s with light wheeling and not being crazy aggressive wit hit off the pavement.

IIRC:

D44 Advantec M210/M220 (F/R)
Standard Width - Some Gladiators, Non Rub 4xe, and Rear Axles in some other Wranglers (I think, I'm sure someone can clarify)
Wide Track - Rubicon
Wide Track, FAD Delete - 392 - This may also be HD with Cast Knuckles
Wide Track, HD with Cast Knuckles, and possibly thicker Tubes - XR, 392 XR (Fad Deleted)

CV Axle Shafts instead of U-Joints in MP3022 and MP3022OR transfer cases (anything full time)
Wide Track is 1.5" total wider (.75" each side)

I would assume Willy's XR is wide track, but not sure.

Oh wow, so the wranglers with the XR package have stronger axles? Dunno if I read that correctly.

Not positive on the tube thickness, but they do have the cast knuckles.

The High Altitude trim has the Dana M210 wide axle on the front, and Dana M220 on the rear.

I have the 2021 High Altitude 2.5 Teraflex and 35s. My spec sheet says front m210 wide and rear m220 wide. Are my axles the same width as the Rubicon?

FYSA, I’m pretty sure the FAD delete axles just have a plate installed. The hole is still there, so don’t think you’re getting a baby Dana Ultimate 44 for cheap.
