look for the ratio on the tag on the axle diff.............it will tell you what youve got in it.

There is no set ratios for any XJ, YJ, etc... Depending on the options it has it could have 3.07's, 3.54's, 3.73's or if it's a 2.5L 4.10's. I believe 3.73's only started appearing around 1991 so if you have a earlier model, you'll more then likely have 3.07's or 3.54's unless it's a 2.5L which would have 3.73's and 4.10's even back then.

On the diff there should be an ID tag. It will read something like xxxx 307 xxxx. The middle set of numbers are your ratios.

This should be in reference to high pinion vs low pinion. High pinion are refered to as reverse cut gears.
