I wonder how they got those Mogs to handle the toque I thought they werent that strong .
Those look like u1300 which are on the same level as 2 1/2 ton rockwells w/ 47spline 2" axle, pretty much bullet proof.
The thing with mog axles is they can handle a ton of torque being portal axles it place much less stress on the r/p and axles. The problem with them are they all roughly 7+ in the gear ratio, youd need 54" tires just to cruise at highway speeds.
I do think they are 44" boggers not 54" the 54" boggers are wider and the tread is more open
