    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.

      No more squeak

      Had a squeak somewhere and haven't heard it since installing the new belt. 10/10 would buy again.

      Perfect fit.

      Previous belt was frayed and squeaking horribly until the car warmed up to operating temp. Took 20 minutes to put on because I've never done it before. Needed an extra set of hands to hold the tensioner off the belt, but not a big deal. Fixed all the noise the old belt was making.

      Great product!

      I had almost 100,000 miles on my Bullitt Mustang's original belt, so it was definitely time to change it. Great price, great fit!

      Too hard

      A little harder than I thought it would be. I woulda have liked it a little bit more soft. But seeks to be holding up fine.

      Much Needed

      Left work on a Saturday morning and heard a nice high pitch squeak, immediately realized my belt had finally gone. After looking around at local shops, this was the cheapest Motorcraft belt I could find. I placed my order on Sunday and it arrived by Tuesday, very pleased with the shipping. Install was a piece of cake with it only taking approximately 15 minutes. I do suggest you watch an install video before hand, take pictures of how your belt is set up before replacing, and have an extra set of hands to make it a bit easier. Overall, great fit, easy install, and not a bad price. Would personally recommend buying this belt if you're in need of a replacement.

      Good Replacement Belt

      My old serpentine belt definitely needed replacing, so I bought this. It fits perfectly and so far it's still in great shape; no chips, cracks, or fade marks. Motorcraft is the way to go!

      Don't hesitate, this is the belt your car needs.

      Easy to install. Installed with a new tensioner assembly. No squeak, or noises from the very first start. Excellent.
