They probably just pass on whatever everyone else is using, made in China. send them an email or call them and ask where they are made. Just about anything I've bought offshore, the boots have cracked before I got to drive the car. My ball joints were made in India, I should have sent them back, the studs were too tight, I like to be able to turn the stud so I have best access to the cotter pins. I would consider PST, but would bet where they are made.
