Idk what they consider “upgraded”. I bought the ones zzp called upgrade parts because mine were worn out and clunking. The links they sent me were clearly from 2different manufacturers. I was not impressed and I couldn’t see any difference from the ones I took off other than the “pair” they sent me were different from each other . I have know idea if the ones I took for were oem or not.
