Yeah, you'll have a hard time finding superior quality struts that are not assembled in China, Africa, Spain, Mexico, Brazil, Japan, or assembled in USA with foreign parts, even if you go with KYB, Monroe, Tokico, etc... More parts are made in China now, and even trusted brands of any auto parts are switching to cheaper Chinese contracts.
Sensen struts have Japanese made NOK seals, and are covered by a lifetime warranty.
