Speedometer Driven Gear Calculator, The Speedometer Gear Calculator is an essential tool for automotive enthusiasts, mechanics, and professionals involved in vehicle maintenance and customization. The Calculation is based on knowing the number of revolutions required This calculator helps determine the correct speedometer drive gear based on tire size changes and axle ratio. A vehicle uses the speedometer drive gear to estimate its speed based on Calculate the correct speedometer gear size for your vehicle. Speedometer Driven Gear Calculator Driven gear tooth count = Drive Gear tooth count x Axle Gear Ratio x Drive Tire Revolutions per Mile (or 20168 / Drive Tire Diameter) / 1001 This will calculate the speedometer driven gear needed to properly calibrate your speedometer. A higher tooth count drive gear increases speedometer reading, while a lower tooth count Speedometer Gear Calculator Explanation This simple calculator does the math to help figure out the 2 gears that are needed to make your speedometer work Home Speedometer Gears Formula for Calculating Speedometer Gears The following formula will work for any GM, Ford or Chrysler vehicle and is very useful when The calculator may provide various pieces of information, such as: The number of teeth needed on the driven gear (the gear that meshes with the drive gear) The ideal The driven gear, or external gear, is the removable gear that is in the housing and the speedometer cable attaches to it.
