Avalanche Engineering made those axles for a while, along with some other cool parts. They are one of the many companies that were the big thing for a year or so. They probably sold the design to someone else.
2.5 ton chunk, 4" x .5" chro-mo bolt on tubes, 300m 40 spl shafts w/ removable billet yokes, 1510 joints, f-450 outers
