Is it enough? Or pr 60 ?

 

the housing shouldnt be a problem. look at shafts and ball joints too. go rcv's and prosteers and u should be good.

 

I have a PR44 with the heavy duty axle tubes, RCV, Reid knuckles, Prosteer ball joints, ARB and beat the crapy out of it with my heavy 37in Toyo tires and heavy beadlocks. Only regret I have is now I want 40's... I guess I should have gone 60 up front from the get go!

 

what makes u so sure u can't do 40's on the pr44?

 

I guess my first reason as to why I say this is I have seen the Dynatrac sponsor say if your going to go with 40's safety get he PR60. Not saying the the PR44 can't handle 40's themselves but some of the reliability will be lost and that is why I bought them in the first place. I wanted to not worry about my axles while I'm miles out in the woods. My jeep also is in the 7,000 pound range and most JKU's are not. So for me the added weight, my driving style, and the type of trails I wheel on In Tennessee all make me question if the MY PR44 will hold up with 40's. if the Dynatrac sponsor feels that I would be fine then that would make me feel a lot better about moving to 40's next year. So my conclusion. Yes I think he PR44 will handle 40's. but maybe not for everyone.

 

37's and PR44 beat the hell out of it and don't worry about it

 

i was talking to mel at ore about 40's on my rig. he said no problem. would a 60 be better? sure. but the pr44 will handle it without issue. my pr44 is being built basically like yours with rcv's and arb etc. btw, mine is a 2door that is not even close to 7000lb.
well said.

 

I have been running the PR44 with 37's for about 6 mos and wheel it with no issues. I run stock shafts (for now), pro steer ball joints and the factory E-locker. I will be doing 40" trail grapplers when they are available. I wheel mostly hard trails, Big Rock Gardens, and lots of Mud. I usually have every spare part, tool, camping gear, food, two children, and my wife in the rig (which is a JKU, schrockworks bumper, winch, etc.)

 

Running 37's on a properly equipped ProRock44 is a great combination. Running 40's? Marginal.

Running 40's on a PR44 is kind of like running 37's on a 30: Some people can make it work but it's not anything close to ideal. The problem isn't the housing but the axle shafts. Even with RCVs we start seeing shaft failures with 38"+ tires on a heavy rig and a reasonably aggressive driver. We all have a lot more fun if we're not worrying about breaking parts. Personally, when I approach a challenging area I want to wonder 'Will I make it?'. Not 'Will I break it?'.

 

im running 37s KM2s on my stock rubicon D44s all i have is evo sleeves and gussets on the front. I havent quite beat the hell out of them but i have worked them pretty hard and no problems here. If 37s is a big as you ever wanna go i say save the money till you break it then upgrade.
