I don't see RA as being liable for a faulty belt tensioner, they didn't make the part, they are just offering it for sale. But I, personally, for years do not buy ANYTHING with the Gates label after lousy experiences with serpentine belts that dry out and crack after 2-3 years, early malfunctioning locking gas caps, wrong radiator caps and some other items I can't even remember anymore( I do think their industrial power transmission belts still have a good reputation). I view them as marginal quality parts in a Gates box. Maybe not all of their parts but again the prevalent aftermarket 'crapshoot' of aftermarket parts and not being able to trust old brand names. When replacing my belt tensioner I bought OEM Mazda even though Gates was significantly cheaper. Rant over.
