And not back up your statement. Second yes while AMS is a shady poor quality co. and everyone is jumping on the "I hate AMS bandwagon" (rightly so imo) his question is not being answered. People are running straight pullies with out issue. Some though have had issues, as with any product some hiccups occur. I would stay away from AMS but in general you'll typically be safe with a balanced crank pulley/ pulley set. Stay away from under driven water pump pullies.
