PRODUCT OVERVIEW

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.

I have a 91 YJ. I would like to put on 35" tires. gears are factory. how do I know what they are.

Asked by D from on

Hi D, The Jeep YJ's came with several options on gear ratios, the easiest way to determine what you have is to give the VIN number to a Jeep dealership and they will have that information. If you don't have the serial number, you'd need to count the ring and pinion teeth. Thank you for the inquiry.

Hi....I have a 91 YJ wrangler with 4.88 gears and 35" tires. I think this is the speedo I need. I am a little confused on "long" vs. "short" Thanks!

Asked by Jeepforever from Horseheads, NY on

Hi Jeepforever, Yes, this 39 tooth gear from Rugged Ridge is correct for the '91 YJ w/35" tires and a gear ratio of 4.88. The short shaft versions of the gears were only used from '93 to '06. Thanks for the inquiry!
