I wish I could get my hands on a couple of crates full of the Dana Venezuela HP 44 that is only slightly larger than the HP 30. It was the OEM supplied front for South American build XJs.
A lesson learned—keep it light and nimble!

I'm sure I'll be told I'm a dumbass but I thought by going to the 30 spline axle shafts that got you the same size as a Dana 44? The R&P size you can't do anything about.
I think you are headed in the right direction and know you will make whatever axle you get like NEW before it's bolted into your rig.
Hope to get to do some wheeling with you sometime...
I asked ECGS about specs on the axle set and they could not give me the axle diameter. My assumption is they are the same, or nominally larger. Once I get them, I'll measure to confirm. What I did find out was the shafts they sell are Yukon, which doesn't surprise me.
I think the 30 spline '30 axle shaft is something close to the diameter of the 44. The other thing that is not apples to apples is high pinion vs low pinion. In the front, a high pinion is stronger than a low pinion (the reverse is true in the rear). Many years ago when I put an HP pro-rock 60 in the rear, I was told by Dynatrac that it was something like 20-30% weaker than the low pinion. I did smoke that thing a few times.
As I understand it, going forward in the front, low pinion gearsets tend to separate under load, where high pinion gears tend to draw together. Without running a load bolt like I think the Currie stuff does, I believe that's the difference.
But to your numbers, nearly and inch and a half in ring gear diameter is a lot to make up.
It is as simple as the angle of the teeth in a gear set. The drive side is roughly perpendicular to the base of the gear and the matching angle on the pinion means there is nominal deflection under load.
The coast side is angled by a lot more so under load the teeth ride up the angle and move away from each other.
Refrain from trying to recover someone stuck in the sand by pulling them out in reverse. Other than that, HP30 gets my vote.
This is what I've been told also. And the fact that I've broken 3 R&P gear sets in my CRD60 I guess is further proof.
Hopefully the Super60 R&P plus load bolt will cure this.
Since I'm going to re-gear to 5.13, I'm wondering if now would be a good time to swap out the factory rear Rubicon air locker for an Eaton Elocker? The factory locker works fine, but I've already had one grenade and the thought of another one going out is ways in the back of my mind. I was lucky before, because I had a spare. I do not now and parts are almost impossible to find.
Now we know why your avatar has a big white beard, Blaine…
I have a spare Rubicon front locker. Can that be used? I've seen conflicting information there. If not, let me know what you can find for the rear!
It can be, it never should be. The 2 pinion design is far weaker than the rear design and the only conflict is due to folks doing it who don't come back later and explain the mistake they made. At least 2 of them are on this forum, were warned, did it anyway, broke them later and then didn't fess up. I know one of them didn't simply due to the fact that I was the one who told him not to do it.
I'll dig through them today if possible and see what I find.
Yes, and I had one from them. The saddest one is Superior had a couple. They forklifted one down off the top of the rack, mowed all the mounts off of it and stuck it under the nephew's piece of shit YJ because they needed to make Moab.
And Currie was selling them at a reasonable price. It's a shame that they were never offered in the states as an optional h-d package for the jeeps.
Its what the Rubicon should have come with, instead of the pseudo 44 that it actually DID come with
Well this sucks. I can't get a set of Revolution 5.13 gears and the Elocker has been back-ordered for a month, with no delivery date in sight. Top that off with the fact that getting a Dana 30 Barnett cover is also impossible, which means I won't be putting a HP 30 together for several months.
It does look like I could get Yukon or USA Standard gears, but those are more expensive than revolution, and not as well made. Additionally, I found ARB lockers in stock, but I've never installed one and getting it setup correctly is something I'm not willing to compromise on!

Pretty sure all my Currie axles came with USA Standard gears. But welcome to my world of waiting on parts.
I’ve been kinda searching on/off for a front rubi housing for a while. One of my C’s is bent.
I’d like to sleeve and gusset the housing and then swap over the internals.
The other problem is finding someone local to sleeve and gusset the housing.

I was trying to get 5.13’ and install kits from Revolution. No ETA.
