Interesting 1/2 ton u joint upgrade

Noticed Dan Dibble talking about this places axles for his Rockwells and went to take a look. Looks like they have some half ton upgrade with double splined shafts and bolt in u joints. Anyone know anything about this place or these? Yes I know about Sunray Engineering doing a similar setup for 60s.

Okay, I'm going to ask a dumb question. What's the advantages to the axle joints? I understand the bolt-in u-joints, easy to change but are the stronger? What is the double splined thing about?

the shaft is all buy its self. the yokes can be changed from the shafts. and a big wast of money in my eyes. if it gets that bad the 2 1/2 ton rockwells will be under my ride.

The advantage I see is if you don't twist the splines you and you bust a Ujoint you just change a yoke instead of full stub or inner shaft. No idea about strength on these.

The problem still lies with the U-Joint being the weakest link. Any time there are needle bearings involved, they will deform causing failure of the part (for our uses).

I also have a problem with the double splined shafts. It sounds like a great idea, but from what I have seen, it makes the whole assembly weaker when used with an alloy aftermarket joint. The shafts are plenty strong and more more than likely never have a problem, but the yokes tend to split in half.

I seriously doubt these shafts are just a whole lot cheaper than Superiors, and Yukon shafts might even be less expensive. Anyone know a price on these?
