speedo question??

I have a 01 TJ on 33's and need to change out my speedo gear. I know it should be 31 tooth gear but is it a long or short shaft? thanks

Short shaft. Check out http://www.transmissioncenter.org/speedometer_gears_for_dodge_and_jeep.htm So you do have 3.73 gears?

So 4.56 gears and 33' tires would be a 39 tooth gear. I have 3.73 gears and 32's and no problem doing 85+

I see you have the 4 banger. I would regear to atleast 4.88 or maybe 5.13 for the 33's
