From anecdotal reports, it appears that some well-regarded manufacturers (including Lemforder) are now sourcing some of their parts from China. I would think (hope?) that the big name companies would keep tight reigns on the QC for parts that will ultimately bear their name. But who really knows?

Time will tell if it is the same sub-par crap with inferior metallurgy, bad rubber compounds, and lousy dimensional control as items sold by URO and other known peddlers of garbage parts.

Some Chinese manufactured parts can be okay, but their Western "partners" need to keep an ever vigilant eagle-eye on them every step of the way to assure that quality standards are met. IMO, that doesn't happen too often. Maybe in the electronics assembly arena, but in car parts? ¯\_(ツ)_/¯
