So far I've heard the axles are very Dana 44 like but not an exact duplicate. I've heard that the axles are 19 spline and 31 spline but I'm not sure if thats the inner shafts or outer shafts or both. Although on the AVM locking hubs website they list the old mahindra models as a 10 spline outer hub. Which also explains why I've seen a set of Warn locking hubs on a Roxor so fast because that would mean its an almost identical hub design as the early CJ/M38 jeep hubs. I've also seen that OX locker has gotten a hold of an axle and have already made a selectable locker for it, considering maybe the fast release of these products I have to believe the axle is very close to the old style D44 design. I emailed an OX locker rep and they say the axle is pretty stout for its size and engineering. A decent axle and stronger then a D35 per say so I think these axles could be totally liveable with a 33" tire and probably a 35" tire with a soft foot. The other nice things I've noticed about the Roxor axles is the drains are cast in the bottom of the diff and the fill plug is in the cover so there's not a need to pull the cover for every fluid change. A nice touch. If anyone else has heard more specifically on the axle design or possible options to be available, please, do comment.
