Why? A 14 bolt shaft works so well cause it backed up by the rest of the axles strength, you add those shafts to a lighter duty axle like the 44 you wont gain anything but a shift in where the next failure will come from, the R&P.

I put the hole weight of my Jeep onto one wedged 14 bolt shaft to the point were I did not move forward but upward. Yes the front tires came off the ground trying to unwedge that rear tire, finally it broke free. The rock was touching the inside of the rim in that pic.

So ask yourself, yes you will have 14 bolt shafts, but what will the rest of the axle handle, oh and when we were done for the day I pulled the shaft figuring I had a twisted spline and of course the spline were fine.

Nothing beats a 14 bolt, period. Build it right the first time and it will last for years.

The plan is to take a Currie Rockjock 44 (uses JK44 gears) and weld the spindles on to make it full float. The operating diameter of the 14B shafts is large enough that I can get them shortened and resplined to the 44 30 spline pattern. I only ever plan on running 37's so I'll have almost 1 ton strength and 44 clearance. The front is going to be a hybrid too, HP44 housing with D50 gears and 35 spline D60 shafts and outers with a 35 spline ARB

The neck in the shafts will be the breaking point on the rear 44. If you decide to run a 35 spline rear 44 the pinion becomes the next weak link. So even your idea of a 44/50/60 the 44 pinion is what will give up first.

I'm not here to tell you how or what to fab, but a 60/14 bolt shaved ( both axle's ) will give you plenty of ground clearance with 37's. Heck I got friend that run 37 red lables on one ton's with no shave.
The minor difference in ground clearance is not worth giving up the strength and if you stick to a one ton platform and not a "maybe one ton" you can grow into your axle's.

Build the 50 front if you all ready have it into a 35 ( 35 spline side gears machined into the 50 carrier welded into a spool ) and at least you will have a 35 spline 1.5" axle in a larger ring gear axle than the 44.

Again not trying to tell you how to build it, just search pirate or were ever and see who built a hybrid axle like your talking about, see were they are with that front, either they out grew it fast or it never really lived up to what they wanted.

Jason.

One other benefit of using factory one tons.. off-the-shelf parts.

Why not a sterling? Has the 35 spline if memory serves me and clearance of a 60, disks, all the bells and whistles. Let me say that two weeks ago a samurai on d44's had a bad day on 36 iroks on a trail. Broken shaft which wobbling wiped a ball joint. I know it was a front, but smaller tire, lighter rig, etc. Jason has saved me from wasting astronomical amount of money on something (more than once) that would have worked, but could have been a lot better. As much preaching as one of us could do may or may not sway your build. But if it helps its for the greater good.

I still will eventually build 609's, 35 splined, with 10" gears, but that's still more effective than d44 tenfold. You You could do a Jana 54, but then you shifts back to the skinny shaft idea, or a pinion. Best of luck to you!
