USA industries reman starters and alternators are rebuilt in the USA. What I do not know is how long they will last. I would always be given one to install, and it would work well enough for the customer to go on their way.
One thing I liked is that they never carelessly sprayed them with cheap paint. As I like to say, if you can't do something as simple as paint properly, what else can't you do correctly?
I never heard of them having 100% new starters. If they are made in China or Taiwan, look out! I would often see China or Taiwan made starters at Hot Rod shows, and the case always looked like it was stamped improperly. If you can't stamp a piece of steel correctly, what else can't you do?
