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.

2001 XJ, work perfectly

Works like it is supposed to. I have a 2001 XJ. Not sure why 4wheelparts doesn't list this as compatible if you do a vehicle specific search

Works great

Took about five minutes to install. Make sure you put retaining clip in the right slot on your Speedo Sensor. It's marked for different size gears.
