Hey guys ive finally decided to break down and do a gear swap on my 93. im going from the stock 2.73s to 3.73s ive tried to do some research on the speedo gear and its got me confused :s. do i need to get another speedo drive gear and speedo gear or just a different speedo gear? if so what ones do i need? everything on the car is stock but the motor. Thanks for the input!

I just fixed my speedometer in my 90 last week, after a transmission and gear swap. Here is a link to the site I used. http://www.transmissioncenter.net/sp...n_______va.htm
Or you can call them at 1-888-877-1008 and ask for Jim. You will need the year, make, and model of the car, type of transmission, rear end gear, and tire size. They can tell you exactly what drive gear and driven gear you will need. If they have them in stock they can ship them right out the same day.

No problem! Hope you have as good of luck with them as I did.

sure depends on the transmission...5-speed is a breeze...AOD uh not so much.

the years are taking a toll on me.

but im gonna say that 3.73's arent correctable in a '93 without a teardown. an AOD thats for sure....a T5 is iffy

you failed to state which trans you had....which happens to be a big deal

you never wanna use the 23t white gear from a jeep, ideally you want a black 6t driven and a yellow 18t drive for a T5

an aod ???? just save for your next rebuild, forget about ratios

I went 3.73's with AOD & bought a black 23T (for Auto) from LRS as a temporary get me close (when I drive 60 it shows 65mph)...I did hear that they may not last long, but so far a couple thousand miles. That black 23T easily goes in the speed sensor & it only cost $15. I kept the original gear for the 2.73's so when I can get to a speedometer shop, they can do a custom gear reduction box (to my original). It's a 6 hour drive for me to the Portland, OR area where the guy @ the speedo shop said it takes about an hour to dial in the speedo on the dyno for perfection ($160). That's not bad, but I gotta get the car there.
