My bad.. I was on the understanding that the owner of Alloy USA came from Superior and bought/made his axles the same place Superior did, which is over seas.
Looking on both websites, neither say they are made in the USA, or at least no place I can find.
It really doesn't matter, IMO, they are all great axles.
Superior has two lines, One made in USA (Foot Axle & Forge in California) and the other from India. All Alloy USA is from over seas (India I think). All of Randy's stuff is from India, I have met his manufacturer at the SEMA show. Also at the SEMA show I witnessed the testing (to failure) of Spicer, Yukon, Alloy USA, and Superior axles 4340 CroMo front axle shafts with Ujoints. I don't remember the exact numbers but I remember the order of failure. There was a huge difference between all the aftermarket axles and the stock Spicer stuff. This was the pecking order from best to worse of the common 4340 shafts:
1. Superior
2. Alloy
3. Yukon
4. Spicer
Longfield Super axles were also tested, but these shafts are for CV applications such as Toyota and some specialty Dana 60 axles. The Longfield’s are made from 300M and tested above the 4340 products for strength.
The Spicer is not 4340 CroMo and is way down in strength from the other axles.
I recommend using the best product available whenever possible for off road abuse and having spares on hand for any areas that experience repeated failure for the following reasons:
1. Trail repairs are a pain in the butt and generally slow a whole group down waiting for the repair.
2. Sometimes you have to leave your vehicle and come back the next day for repairs.
3. If your in a competition, you have just lost unless you can make the repair quickly from spares on hand.
4. It can ruin your whole trip if you can’t get parts and are done wheeling for the duration of your vacation.
5. I HATE CHANGING AXLES.
I sell all of the above products and will match any verified competitors pricing. I have gone wheeling or met with the owners of all the above companys except for Spicer. I am on a first name basis with the owners of these companys. I should be able to resolve any problems that you may have with any of the above products and will work to solve any warranty issues from any product purchased from me. I also agree with Wayne that all are good products easily exceeding stock type axles for strength and quality.
