These TCI Ford speedometer driven gears will allow you to calibrate your speedometer readings based on the tooth count of the gear. They are made of high-strength plastic and are available with a variable amount of teeth to fit your applications needs.
This is a retro-fit gear to allow the speedometer to function with 3.73 and 4.10 rear end gears. Since the gear tooth pitch is slightly different than OE, the service life of this gear is limited to less than 25,000 miles
