Dynatrac ProRock JK Axle Swap
One of the reasons I bought a Rubicon, was for the front and rear dana 44 axles equipped with electronic lockers. That being said, the trails I have been going on are getting much more demanding, and I want a bit more peace of mind out on the trails.
It's time for an axle swap! I've heard many Jeep folk say, if you're doing one-tons, you MUST go 8-lug; and if you're going 40s (or bigger) and have a roaring V-8 under the hood I agree. But given that my Jeep is a 2-door, and it will never see a tire larger than 37s...I didn't see the point of spending the extra $10,000 to go full one-ton. Dynatrac has the perfect axle set for projects like this. I am pulling out the Dana 44s and replaceing them with a set of the "Serious Performance" ProRock Axles from Dynatrac.
This package allows you to run 37 inch tires with confidence, and won't be quite so hard on your bank account like a full one-ton setup would. With this package, you get an assembled ProRock 44 Ultimate front axle and the revised ProRock 62 semi-float rear axle. My axles came with 4.88:1 ARB air lockers, 4030 front & rear axle shafts, HD Ball-Joints and 1350 sized yokes. While my e-lockers worked perfectly everytime, I have grown tired of waiting for them to lockup; and I'm really looking forward to the instant lock of the ARBs.

My pleasure; it was a pretty fun upgrade for the most part. The end result was worth all the physical pain it caused me ahhahah!
Great video

Thanks! It was an adventure from start to finish. They worked flawlessly in Moab and my latest trip to Southern British Columbia. Super happy with how everything is workin. Thanks for the feedback. Appreciate it.
Great video once more! I have the same setup as you in the rear and love it! Because things broke at different times, I have the Spicer Ultimate Dana 44 up front. At least it gives me some redundancy with having an air locker in the rear, and an e-locker in the front, but I wished I had Dynatrac on both ends. I went with the Falcon shocks after watching your video about them, and I'm glad I did. What a difference it makes indeed. Btw, did you weld the shock skid-plates or just bolted them on?

I just bolted them for now. Will weld them on when I get home from Moab. That being said, they haven’t moved.
Well done sir! I'm in the market and want 60’s on 40's (currently have stock Rubicon axles on 37's). After your Moab trip, would you recommend doing 60's front and rear?

If you’re going 40s YES to PR62s front and rear. For me, 37 is max; I would have to give my garage a lift-kit if I had 40s 🤪 in Moab my PR44U/PR62 combo was absolutely dialed. Loved it. Also, for 40s it’s best to have hydraulic steering.
Great video with lots of detail points. What type and brand of diff fluid did you use for the front PR44?

I use Canadian Tire brand non-synthetic. If you’re in the USA, Castrol would be my go-to. Also, you do not need a limited slip additive since these are open differentials.

I'm in vancouver. I will definitely look up at CT for the fluid. Thanks again

@@OFF_THE_HWY_ADVENTUREit’s good stuff; my pal Jason has been using it in his ProRock 60s for 10y and they’re still going strong. His is a daily driver on 40s :P

I have PR44 as my front axel but not sure what type of fluid to use. So far I use 85w90 (I think that's the right type). I also have eaton e-lockers with 37's

I use 80W90 front and rear; nowhere near hot enough for the 140 weight. Double check the eaton manual; I don’t know anything about them or their requirements.
