It makes perfect sense to me. I'm not from the US, I don't need to support your economy. I have no problem running Chinese or other springs if the quality is there and neither does Betts. Yes, Betts is a simple answer but it still doesn't tell me where they're made.
Straight from Betts' website;
"In recent years, import leaf springs have emerged as an alternative to domestic manufactured products. Import product is increasingly recognized as a cost effective alternative at an acceptable standard of quality, but many companies are reluctant to engage in import programs due to risk, unfamiliarity and lack of infrastructure. Betts has developed and qualified high quality import sources for high quantity applications where the economies of import supply become important. We coordinate design, production, testing and distribution as value add services for our customers."
