I know this post is old, but I worked at Axletech for 16yrs. They never sold Military parts to civilians. Much may have changed in the last 10yrs since I left. The gear reduction came as planetary wheel ends. They were making wheel end mounted portal drive boxes, but it added several inches in lift ( off road rock climbing stuff). Yes they acquired US Gear, in the Chicago area when I was there. They make gears for many other manufacturers also. The MRAP axles are very heavy, I am curious as to what people are using for wheel ends and axle shafts. AxleTech is part of ArvinMeretor again, I believe. This would open up much more on-highway capability, but 99% was very heavy duty stuff.
