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.
Is it the right gear for my Jeep Wrangler TJ (Canada)?

I have a 1989 Jeep Wagoneer Limited (XJ) the technical description says it will fit, but when I do the compatibility check it says it is not for my vehicle. I am confused now. I know I need the long shaft and a 38 tooth will fix my speedo reading.

Thanks for the question. This would be the correct 38 tooth long speedometer gear you would need for your 1989 Jeep Cherokee.
