^ he is right on the JK 44. If you build a JK 44 right, it can be stronger than a standard Dana 60 and not really costs much more. Go look at some of the mud trucks. Some of those guys use a built Dana 44 instead of goign 60's or Rockwells. They seem to do fine but it all comes down to how you wheel, not what you wheel.

If I ever do an SAS, I'd like to get the aftermarket JK 44 (I think from Currie or Dynatrac, I can't remember)
