Dynatrac ProRock 60 and ProRock 80 axles are the bomb and I wouldn't hesitate to recommend them to anyone. They really have held up great to the abuse I've put them through over the years and I love them. The ProRock 44 we ran in the past and am running now have been great too and I would definitely recommend them to anyone who plans on just running 37's and with a factory rear axle. That being said, I'm a little hard pressed to jump on board with this new axle or at least, at this time being that it's so new and completely untested. In the end, you're still getting a semi-float rear axle and one that's only made by Dynatrac. Also, the cost of it along with a PR44 will set you back about $13k. I hate to say it but a Dana UD60 front and rear will only costs about $1k more. Sure, you have to get new wheels but then, I've never heard ANYONE who really needs to be running bigger axles to bitch about going to 8-lug. Plus, the benefits you'd get with UD60s such as a bigger ring and pinion, bigger shafts with more splines, locking hubs up front and of course, MASSIVE brakes are well worth it.
While I'm sure there is a market for these, it is my opinion that you'd be better off saving for a set of ProRock 60's or consider UD60's instead. Again, just my 2¢
