Master Pro Select = Cardone Select
I can't confirm that this is true or not, but I have been told by three different people at O'Reilly auto parts, that the store brand name "Master Pro Select" CV axles are made by Cardone. The Select CV axles come with a lifetime warranty and are brand-new not remanufactured. I also called the Cardone tech-support line and he confirmed that the Master Pro Selects were made by Cardone. I hope this helps.
