    Will this fix the speedometer reading by itself or will I need to buy the drive gear also

    Rafa

    • The Ford Speedo Gear will be all you would need to correct your speedometer reading. However, you will need to get the right tooth gear for your set up.

    Will this work with 373 gears ? If not which one will

    Oorah

    • The Ford Speedo Gear - 20 Tooth will not work with your 3.73 gears. As far as which gear you need will depend on what drive gear you have. If you have an 8 tooth drive gear there will not be a speedo gear for 3.73s. However, if you have a 7 tooth drive gear you will need the 21 speedo gear. https://www.americanmuscle.com/speedo-gear-21tooth-auto.html

      SPEEDO GEAR

      THIS IS A MUST IF YOU HAVE UPGRADED YOUR REAR GEAR. MY SPEEDOMETER WAS OFF 10MPH BEFORE THE SPEEDO GEAR CHANGE.

      It's great that you can still buy OEM parts when performing upgrades.

      Just what i needed.

      I bought my car used and knew the speedometer could not be close to right. With the help of gps unit i found out that with my speedo at 80mph i was going 62mph. A little use of an online calculator and found i needed a 20 tooth speedo gear. It is an OEM ford part and came with the clip. Took about 5 mins to install, once i had the car in the air. Super easy. Thanks American Muscle!

      20 Tooth Gear

      This product was in the original Ford bag, came perfect, arrived on time, and worked perfect. It was also cheaper here than anywhere else.

      Speedometer gear

      The gear was a simple exchange. There obviously was no performance gain, but now I can drive the speed limit without fear of being ticketed.
