When changing tire size or axle gear ratio's your original speedometer gear will not register the same MPH as it did with the stock gears and tires. The MPH will either read higher or lower than what the vehicle is actually traveling. You will need to change the speedometer transfer case gear to the correct tooth count to obtain the proper MPH reading on your Speedometer. Use the Tire and Gear Ratio Chart to determine which Tooth Gear you will need to correct your MPH speedometer reading.

Questions & Answers

  • Q:

    "Hi What is the number of teeth I need and the part number of the gear for a Jeep Wrangler fitted with a NP231 with 33"" tires. Also I believe there is a bracket that you can buy after a lift that realigns the shift lever resulting in better engagement of the transfer case"
