Most are, particularly the generic brands, but one like GMB, Paraut and a few others which are OEM manufacturers, all come from Japan and are the pic of the bunch.
Where i am, we primarily have a focus on OEM and genuine boxed items. Where we have aftermarket items, they still tend to be either Japanese A/M for Jap applications or European A/M for the likes of Scania, Volvo, Mercedes, Perkins, Ford etc. Its just not worth the problems. You have no idea how much bad Chinese product I come across every day where sellers are in it for the buck and the customers just want to save a buck!
