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

    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!

    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.

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