Possible PR44/60 upgrade?

My fiancée and I have been tossing around the idea of upgrading the axles on our 2012 JKU Rubicon. Right now we’re running a 3.5” MetalCloak lift with 35s, but we’d like to step up to 37s and be able to run them confidently. I can say for sure we don’t plan on going any bigger than that.



We use our Jeep the way it was meant to be used – driving it hundreds of miles, hitting some challenging trails, and then driving it home the same weekend. We don’t trailer and don’t plan to. On the highway we take it slow and steady, and off road we don’t beat it too hard.



Before anyone suggests full-float 60s, I should mention we’re both in our mid-20s and don’t have $20k+ to drop on axles, wheels, steering, etc.



Right now I’m really liking the Dynatrac Serious Performance ProRock 44/60 axle set as a possible upgrade. It’s actually within reach for us financially, and I like the idea of running the ProRock 44 up front.



I’d love to hear what people with more experience would recommend. At the end of the day, we just want to keep having fun on the trails on the weekends and feel confident we’ll be back at work on Monday without breaking stuff.
 
DO NOT DO A SEMI FLOAT 60

Dumbest thing ever invented Ask me how I know. Throw a set of Chrome Moly axles in the 44 if you must and save up for a full float 60 if you think you'll ever need it. Keep in mind you're gonna need new wheels as well and there's no good conversion kit to go to 8 lugs on the 44 front, so now you're looking at a D60 front as well. It's a slippery slope.

If all you're going to is 37's those 44's will work fine. Add hydro steering and you're gold
 
ran my 2010 JKUR over 200k miles with stock rear axle and ProRock 44 front axle.

2018 JLUR still has both stock axles and 100k+miles

both with beadlocks and 37's, aftermarket drive shafts,CM axle shafts, lots of highway miles to and from trails.

pick good lines and bypass lines (when possible) if I feel damage will result otherwise easy on the throttle and pull line if needed.

If I did a PR44 in the front and regeared the stock rubicon rear axle, should I beef them up with a truss or anything like that?

The rear is a true 44 so a truss isn't needed unless you really wanted too. Other than maybe some Chromoly shafts, you will be good. Just know that you WILL still bend a rear axle flange whether it is chromoly or a 60, they will bend. The front PR44 will definitely be fine as is.
