These are great axles for the JKU. I installed this set on a 2014 JKU Rubicon with e-lockers and 5.36 gears. This Jeep is running a MetalCloak 4.5' GC w/Falcon 3.3 shocks running 40' tires. Everything bolted right up with only a few issues. I could not reuse the shock skids due to the sway bar attachment location. I could not reuse the MC tie-rod but the axle set came with a new tie -rod. I wish there was a cleaner way to secure the ABS sensor wires but I made it work. With the built-in caster these run smoother than the Jeep did with the stock axles and 37' tires.

could not be happier
I purchased the Pro Rock 60/ Pro 60 axle package for my 2017 JKU and could not be happier with it. The axles are indestructible for the weekend wheeling I do and give me the confidence to tackle any obstacle. I tow a teardrop trailer with my Jeep and the benefit of the larger brakes is definitely helpful. I would recommend this to anyone considering an axle upgrade.

Great set-up
Really pleased with my Dynatrac axles! Have over 10,000 miles and they have performed great. Everything bolted up as it should have and was fairly easy. They have seen Moab and many places in the Southeast.
Only concern is tierod ends won’t take grease through zerk fittings. Almost like they are plugged, but removed fittings and they are not. Contacted customer service and they looked into it, but never resolved. They even said they blew out their grease gun trying to get grease in theirs. No biggie, as I’ll soon replace anyway.

ProRocks downunder!
We made the trip from Sydney Australia over to the Dynatrac Factory to personally meet the team and get our axles organised.
After nearly two years of ownership i can confirm these have been one of the best upgrades we have done to our Jeep! Not once have we worried about failure during our adventures and they've always got us home even after some tough tracks. We do run 40's off road on these things and the confidence to explore with this setup is everything we would expect and nothing less.
Proud to have these ProRock60's under our Jeep.

Major upgrade for my LJ
I finally bit the ballet and upgraded my LJ to proper axles. I was killing my “built” Dana 44 axles every wheeling trip. These new axles are so much beefier and run very smooth and quiet down the highway. Couldn’t ask for a better build.

Awesome axles
The axle assemblies are bad ass. I did and do still have a few concerns with them. The set I received did not have the sway bar tabs welded on them. Dynatrac did send me the tabs and reimbursed me for the time to weld them on. My left hand axle yoke continues to rub on the Axle tube. Another concern is the paint. Would rather have had bare assemblies and painted them myself if I had known the paint was just going to fall off. Lastly the rear axle studs are to long for any closed lug but to fully seat with the wheels I have. Have seen other people with the same issue. All in all the axles are pretty bad ass.

Prorock 60s
Best complete axle assembly on the market which made the upgrade a no brained for me. Perfect pair imo for my king 2.5 recon, rip supercharged JKU on beadlocked 40s. The purchase and axle option build was a simple process with some of the best and proven products out there. I have installed several prorock axles on other Jeeps and can never be swayed from the brand, quality, and service Dynatrac has to offer. Keep up the good work...

4.9 stars
The whole process was pretty seemless. Ordered my set with Steve who was very helpful during and after the purchase. The axles are works of art and bolt right in. My brother and I were able to get them under my jku in a weekend. Only issue so far was my rear pinion seal started leaking after only 1k miles and a couple outings. But dynatrac was great and sent a new one to my local shop to have installed under warranty.

Only gripe I have, and it's a small one, is I wish they would include some sort of directions/welcome packet in the crate. Had to dig through forums to find there are extraneous things like preferred ebrake line routing and abs sensor adjustments that you have to email and request. Even had to ask for the break in procedure which also included some other install directions. Since this is marketed for people to be able to do on their own in their driveway, some supporting documents should be included.
