Have a look at this new axle design...

Still in the prototype stage, I presume, but the idea is cool. Looks like it could work very well or fail miserably.

wow i want one if its strong... but it would be awsome under my yota.

overthought imo, it has like two double cardan joints/8 ujoints on each side, which is a lot of junk and everything is custom so replacement parts should be super expensive. i would rather have a dynatrac built 60s for thousands less.

while i do think it is better than portals because of torque/wrap problems, i still wouldn't want it.
