Is a Prorock 44 strong enough, without additional brace work, to run 37's on a two door JK Rubicon that gets worked on the trails?

Absolutely! ^^ on a prorock 44, hits a boulder smack dab right on the diff, bounces the tj back and everything. And still keeps chugging Along
I just ordered a prorock 44 from trail jeeps. I talked with dynatrac before I ordered it and they said 37" are no problem and recommended to go with the unlimited housing which is 1/2" thick wall tubing. They actually said it is not really needed for 37's but was good cheap insurance. I went with RCV 35 spline axles and ARB which everyone I've talked to has said should be plenty of axle for 37's
^^^ this is a good setup, I would skip the RCV's though, they seem to be a pain to fulfill their lifetime waranty claim, plus full circle clips are plenty strong and half the price...

Thanks for all the great input folks........looks like I have my plan! Would you guys agree that the rear D44 housing is fine or should it be upgraded as well with 37's?

Understood.....thanks again. Yes I am located in Indiana. No plans on running fast through any terrain but I do plan on moving out west and take advantage of the rocks and more technical trails.
the rear d44 is a true d44 so it can withstand 37's easily.

Also want to hit the Rubicon at some point in life. As with most others I don't want to face another upgrade down the road.....wanna do it right the first time and be done with it.
Any other specific upgrades I should be looking at moving to 37's? Such as steering hardware or whatever?
Your response made me look at Dynatrac's site again. This must be why they don't offer a 44 rear axle housing, but they do offer rear axle shafts. I wonder how the specs of the stock rear tubes compare to a pro rock 44 front? Can you tell if their replacement shafts fit rubicons?
The factory front Rubicon 44 front axle uses 2.5" tubes that are only .25" thick. This is essentially what a Dana 30 uses and that's why the Rubicon 44 is really only a 44 by name. Sure, the diff is still bigger and therefore allows for a bigger ring and pinon and beefier shafts but the "housing" and knuckles are basically a Dana 30.
The rear Dana 44 axle on a JK uses 3" tubes that are .25" thick and that's what makes it a "true" Dana 44. You still will have bending issues if you drive hard and fast enough but for crawling, it'll hold up fine. If anything, were you will see the downfalls of a factory 44 is in the semi-float shafts as the flanges WILL bend with hard use. I should note, the flanges WILL bend REGARDLESS of what fancy and expensive shafts you choose to run. If you play hard enough, the best option is to get something like a Dynatrac Trail 60.
Very helpful information. What would be the weak point in running a PR44? For heavy use per say. Ring and pinion?
