This set is perfect for adding a bit of confidence on the trail.
I have the PR44 and the PR60 in my 16 JK with ARBs,5:13 gears. Easy to install, a couple guys with a little bit of mechanical knowledge can install these in a long weekend.

I’ve had my PR44/60!for JKU for almost 3 years. I’ve been very happy with the added strength, reliability, ground clearance, and performance since these were added to my build. Running 37” tires hasn’t been an issue, and with normal maintenance I’ve seen no issues with the tubes or axle shafts. Build time was a little long, given these are pretty standard, but they were worth the wait. I’m hoping to upgrade to the PR60/60 full width axles when I upgraded to 40”s next year.

Amazing axle set up for your JK
I have the Prorock 44 with ARB locker and 5:38 gears in the front of my JK and the Prorock 60 in the rear with the ARB Lock and 5:38 gears as well. This kit is a major upgrade from the stock Dana 44 Rubicon axles I had, The housings are like armor and the easy of installation is amazing perfect fitment and the welds are a thing of beauty! Thanks Dynatrac for making such an outstanding product, I highly recommend these axles and have installed two other sets in my friends Jeeps.
