How much torque do you think the rear end could handle? If I were looking to transmit "X"-amount of torque at the axle shafts driving sprockets, I wonder what the breaking point would be?  The axle shaft ends would likely be supported as well, in bearings, as to not cause a bending moment upon the gear cases.

It would depend a lot on the rear end. They're not all equal.

Oh, didn't realize that.  My experience with the Powerking's is limited to just the one I've had for a couple weeks.  The narrow rear end is perfect for another project I want to do (~1/2 scale tracked vehicle).  But with a donor rear end.  Not the one on mine.  Width-wise, I'm looking at no more than 4ft on width, including any shaft-end supports.  Hoping to transmit in the ballpark of about 3000ftlbs max.  I doubt it'd ever get this high, but this would be the absolute max it would see.

One reason why I was asking about the Powerking's rear end specifically, is the geared reduction.  That way the differential gears and input shaft aren't seeing as large of a load.  I saw a different candidate a little while ago as well, but it was just too wide.  The rear end out of an airport luggage tug truck.  Had like a 17:1 reduction Rockwell axle (3:1 external reduction that bolted onto input side of diff, then the diff reduction). But it was at least a foot too wide.

Not sure you would get much speed from it if needed. They say a t92 trans could handle 25 or so HP, and many guys have put bigger engines in them. Don't think you can break them too easily.

Top Speed of about ~4mph, so speed is not really a factor.
