        Factory piece

        Does what it's supposed to do. Much better price than at a stealership.

        5 2004 Mach 1 - BellX1

        OEM Ford Part, Lousy packaging

        This is an OEM Ford Serpentine belt. That makes it 5 stars. It was delivered in the cheapest, thinnest bubble wrap envelop I've every seen, complete with two tears. The belt was undamaged, but this kind of packaging does not inspire confidence in my next American Muscle purchase.

      Does this stock factory belt work correctly with the steeda underdrive pulleys?

      • Yes, the Steeda Underdrive Pulleys are designed to reuse the factory serpentine belt.

      Okay, I'm confused. Our '03 GT takes this part number, but our '04 Mach1 takes part number JK6947AA. Is this just the same exact Belt with a different model part number designation? Thank you.

      • I apologize for any confusion, we have tested this belt on the 2003-2004 Mach 1 Mustang and it worked just fine. I am sure why there would be a secondary part number but I can reassure you this belt will work just fine.

      Will this belt work with a procharger supercharger? I have a 2003 GT with a procharger in it, will a standard belt work with this or will I need a special belt?

      • If your procharger has a separate belt drive system, then your kit probably uses the factor accessory drive belt. If there is only one belt for the accessories and the prochrager, that will be a special belt. Most often a spate drive belt is used.
