Not sure if I'd fit at 6' 5", but I'd daily it (somehow) if I owned it. But I'd also daily these two, if I was so (financially) inclined...

Some folks call me special.

The first one is cool.... But the second one . I would have to wear ww2 goggles when I drove it. Actually, why don't I wear them now lol?

But the second one

I know, right? Pursang Type 35, a modern recreation of the Bugatti Type 35, they do it all old school. Buy in is a quarter schmill new, used, a bit less. I would if I could...

This is a fair question.

Couple of thoughts...
Cost. It adds up
Although you get 30 spline inners... you're restricted to 27 spline outers... and they forget to mention... you cannot pull the axle shaft out without also removing the spindle... the 30 spline side is too large to fit through the bore. Still not a terrible setup.

Brennans Garage makes a really cool weld on full float housing end
https://brennans-garage.com/products/dana-44-full-float-housing-ends
you can reuse the factory jeep hubs and spindles... but same problem, can't fit a 30 spline through the bore. You CAN use chevy spindles and ford hubs to keep the 5x5.5 bolt pattern, and the chevy spindles are robust enough you can machine the bore to slip a 30 spline through. But it just keeps adding up.

or go with weld on set 20 axle ends, custom shafts (going to have to have custom shafts on all options.) and a simple semi float design. I've been using semi float axles my whole life without problems. At least right now this seems like the easiest option, leaving monies for an selectable locker.

What would be cool? Some kind of 30 spline unit bearing setup. Maintenance free, clean, easy to replace. But I do not know if I can find a 30 spline 5x5.5 unit bearing. I can probably fabricate the cup for the axle

Yep, prices have really increased. I don't remember what I paid back in the late 90's when I was doing the full floater on a Dana 44. And it was a Warn kit too.
I was running the 19 spline shafts and hubs on my setup.

My family just watched this - catching up on your thread made me think to also bring to your attention for a fun watch:

It was a fun watch! I knew most of it, but learned a few bits. Thanks

Same. I didn't realize the steal of the Ford SME. What a get!

Have you considered a custom built 9"? Lots of aftermarket support, options, builders (or DIY parts), and I think they already use set 20s.

I have actually, with the extremely short driveshaft, I have to balance length of driveshaft vs angle. Check out this little chart.

A ford 9" is about 3/4" shorter from ujoint to axle centerline... which is awesome. but the pinion is 1" lower compared to axle center line. I love the longer driveshaft, but worried that extra inch will eat into my available travel. I'm not smart enough to figure out if its better or worse. I've always wanted to build a 9"

Me either. Maybe one of the other guys will chime in with useful info.

Driving that on those bicycle tires must be a hoot!

So...you engineered the entire modified suspension for this thing on your own?

If you're already talking about welding on new ends they why not use a HP axle if you could find one that would work to help with your driveline angle?
A full width HP44 with the long side cut down might get you the correct offset.

I've been thinking this too! But I can't find anyone that thinks its a good idea. Everyone just regurgitates "the drive side is 25% weaker", but has anyone tried a high pinion dana 44 (or 9 inch)? I believe Currie used to make some HP 60 rear axles, but were they limited to 35's?

A HP44 from a JKR has like a 9" ring gear. Seems like even if it were 25% weaker it would still be plenty for a 2200# mini jeep on 31's.

Years ago one of the 4WD rags did HP44's in a CJ or TJ but they were running 35" tires and a 4.0 if I remember correctly. They ended up breaking the gears in the rear.
But I agree with you that with the weight of you rig plus the HP of your engine I don't see it as an issue...
And I've known a few guys local who run HP44's in the rear of their Jeeps too. I hadn't thought about the JKR I was thinking more about a Ford HP44..
Also if you're really worried about it breaking you do a Jana54 which uses a D50 R&P https://www.jantz4x4.com/jantz.php?p=detail&pro=jana_54 which is supposed to be about 40% stronger than HP44 gears.

More the research, t thanks for the bread crumbs

Sounds like you're overly thinking this. With whatever moderate engine you install, a HP 44 would be a good balance between strength and durability. At 2200 pounds and 31 inch tires, how could it not hold up. Also, you don't seem like the type to follow the herd!
