Well you would have warranty in the beginning if they do become a issue. Daily driving and street use they most likely will hold up fine, Jeep must think they can take it.
The concern for some (me included) in order for the current axle assembly's to take the stress the 6.4 can put through them in certain situations is that they basically need to be as strong as Dana 60's to take it reliably.
1st gear in these automatics is pretty low, the 6.4 makes a lot of tq. You start doing the math even without being in 4 low and putting power through both axles using a 4:56 gears and the TQ the axle shafts, lockers and ring gears can see is significant. The axle shafts should take it, the pinion and ring gear is probably the weakest link in the mix.
I have not found any published data on exactly what the JL axles are rated for. Only First Gen 44 and JK 44. I did find something that said I think it was 8 percent stronger than JK44.
Pretty much if you wheel hard or plan on launching it on the street hard some of us question if they can really take that abuse.
Here is my best objective opinion based on the information I have right now. If you plan to stay mostly stock, primarily use the jeep on the street and moderate trails you will be fine or Jeep would not offer it because it could cost them money to warranty it. If you plan on 37" and its a street queen its probably ok unless you beat on it from light to light all the time. If you plan to wheel hard on bigger tires You should probably not push it on stock axles, they will probably break. People who plan to do this probably will just plan to do a axle swap and know that going in.
At the end of the day don't let the axles scare you away, they are already proven in the JL we will just ask more of them in the 392's so we will see how they do over time.

I have to chime in on this…
I daily drove a 2014 AEV JK with 5.7 HEMI, 4.5” lift, 37’s, 4.56 gears…yadda, yadda, yadda… Dana 44’s F/R (typical Rubicon setup) for 7 years.
I bought the Jeep brand new off showroom floor. I have taken this Jeep to Colorado… Imogene Pass, Black Bear Pass and many of the other “passes” in Colorado, Montana and Moab.
It has seen the mud a few times in GA, but I avoided and still avoid “mud” whenever possible.
The strength of the Dana 44’s are legendary.
IF… you are a “hard core” off-roader… (that’s a BIG “if”) because most of those who “claim to be” are NOT… they think they are, but it’s mostly a “mindset” and very few use their Jeeps to their fullest capabilities.
I too use to be of this same mentality.
I had this unbelievable rig that I thought/knew would go anywhere or at least “anywhere” I needed/wanted to go. It took me places that were amazing!
Long story short, IF… you find yourself tearing up a Dana 44, then I would opt for the 60’s.
This 392 is an amazing vehicle. The power is unmatched even with the aftermarket addition of the Hellcats etc…
The Rubitrux conversions are amazing, many other conversion builds out there are amazing as well, BUT… being that my 392 is FROM THE FACTORY, with a warranty is EPIC!
YES, I got the extended 4 year warranty front to rear for the next 7 years… PRICELESS!
Make no mistake, my 392 will eventually have a larger lift, Dana 60’s, 37’s etc… but for now, I will enjoy this “tip of the spear” Jeep as it is and bask in the glory of a factory warrantied 6.4 HEMI for a little while.
I have since sold my 2014 AEV to a great home.
It has taken me 1500 miles to “bond” with my new Jeep, but IF you are a Jeep person?… it’s well worth the price of admission.

Yeah thanks for the response. No plans to be a hardcore off-roader (new to this). Really plan on some mountain pass in Colorado that doesn’t involve crawling too much or bypass if can.I have to chime in on this…

AEV been putting 6.4 in with stock dana 44 and all different gears and in the over 10 years they did it I never heard of that being a problem.
I had a 2011 5.7 with stock 44 and 4.10's and 37's and in the 18k miles I owned it every stop light acceleration was a 0-60 time trial. No problems other than the red upper arms bushing turned to dust as it takes all the load of the hard acceleration.
Granted it was not a 6.4 but as I stated earlier not a major problem.
Jeep got ten years of AEV's RandD shared with then so they knew what they were up against

I have personally twisted axle shafts in the rear, broken an electric locker in the rear and broken upgraded 35 spline front axles shafts in dana 44's on my 2008 JK with a 3.8 and Ripp supercharger so there not that strong. I'm not saying people don't do it but many probably don't leave the street much. Those that do and were running AEV conversions could afford and probably upgraded axles after the conversions when they broke them. I doubt they would complain to AEV about it.
My 392 makes much more power a lot quicker than the 2008.
