Interesting point about the Dana 30 benefit VS Rubicon axles.
The issue with that is that even on the JK rear 44 housing, the housing itself never really had much of a negative issue. The axle flanges can bend on any semi-float rear even chromoly shafts. So I assume from a manufacturing point of view, there really isn't much demand for a rear 44 housing.
Along with that, I would think most Jeepers that are running 40s are really going to see the benefit in stepping up to 1 ton axles as that is the ideal way to do it.
I understand your point but some of us don't need 1 ton axles but need better than stock Sahara axles. When I bought my JL with the trailer towing package I assumed it had M220 axles. Little did I know it had M200 rear axles. I don't really need the 1 ton but may have to go that way since no one is making a Pro Style 44 rear. I do think there is a market for them but until that time I'm between a rock and hard place.

Is the m200 a Dana 44? I thought all Jeep jl’s have a d44 in the rear.

Is this a d35 or a d44?
Dana 35 Rear Axle
Great video and informative. Was there any chat off camera about the FAD "Front Axle Disconnect" and possible weakness point?
Seeing the front axles have little difference between the Sahara and Rubicon I bet the rear axles are close also and those 37" and 40" tires are hard on the rear as well as the front. Really need Dynatrac and Dana to come out with Ultimate 44 or Pro Rock 44 rear axle. Not everyone wants a Pro Rock or Ultimate 60 rear with it's 6 or 8 lug hubs.

Thanks so that’s a m200 d44! Awesome

There would really be no need to replace it, until you broke it. Maybe you’ll never break it.

Dana 35 Rear Axle
Dana 35 has an oval cover. That's definitely not a 35.

I don't think Dana is using the '44' term like they did on previous axles. That picture I posted is an OLD picture pre-jl conception. Maybe this thread would clear up the 'true' number of the axle:

:cheesy: Honestly, there's nothing wrong to wheel what you have until it needs to be replaced. That's what we did on Moby and Rubicat. This time around, we are being a little preemptive but only because we'd like to kick things up a notch. :crazyeyes:
So you're just doing this preemptively? From all the wheeling and miles you've done on JetLi until you swapped to a prorock, you didn't have any axle damage or imminent failures?
Yup, just being preemptive. We were able to get about 25k miles on Moby's factory front axle before completely trashing the locker for the 2nd time and shafts all in one shot. I'm pretty sure we got about the same or less on Rubicat before we bent her her factory 44 to the point of being unsalvageable. We had 23k miles on Jet's front axle and felt it was just a matter of time before we did something stupid. That being said, no, we did not have any damage that we could detect nor could we find any signs of imminent failures or at least, to the naked eye. Obviously, we had some help getting this PR44JL but part of that included Dynatrac being able to get their hands on our Rubicon front axle for R&D. So, we'll see what they find out.
