Just recently bought my 02 sahara. It has 33's and was lifted. I have a manual trans. I run around 2000 on tach at 60mph 'assuming the speedo was calibrated' any ideas what my ring gear might be?

In what gear 4th or 5th

 

[Dminc1980]

5th

Mine runs at 2200 RPM at 70 MPH in 5th gear and i have 3.73 gearing. 60 MPH in 5th is 1900 RPM so i use 4th gear at 60.

Use a GPS app or device and we can give an exact ratio.

Even at 70 mph, I didn't get out of 4th gear, and RPM's were 2250. My gears were 3:07's, but up grading to 4:88's. Gas mileage was around 17-19 mpg, depending on town or hiway.

Also, If you haven't got the "Build sheets," for your Jeep, It would be well worth the time to request them. They list everything your Jeep came equipped with, at time of manufacture.

You can get the build sheet at jeep.com/jeepcares
Just request one and they email it to you, I got mine in about two hours. All you need is your vin.
