A year ago I was going considering Alloy USA's chromoly axle shafts for my TJ. After a few call to Alloy and Superior I decided to go with Superior for the simply fact that Superior's components are designed, forged and machined in the US. Alloys are designed in the US but made in China. It is nothing personal against China and it people but if we keep farming work out overseas because of a lower labor rate. We will not have any work to provide the US worker. My two cents...
I believe most of the Alloy USA parts are made in India. Not all of the Superior parts are made in the USA. If your are not buying a Spicer, Richmond or Precision R&P, chances are they are not from the USA. Many brands buy the same gears from over seas, put it in their box and call it their own. There is no definate ETA on the 5.38 gears, I bet it will be at least 6 months.
Those of you that think you know everything really annoy those of us that do!
