Stock Gear Ratio on a 83 CJ-7

What would be the stock gearing for a 83 CJ-7. Like 3.07?

I have 3.31s from the factory. I don't like them, but I don't hate them.

You can use those codes to ID your rear end, and hopefully your front end has the same gear ratio. Of course you never really can tell if the PO has swapped gears. I hopped into a CJ-7 one time that had the markings for 2.73 and you couldn't let off the clutch without spinning the tires in that thing, so it must have been running 4.10 or 4.56 most likely.

Alright thanks for the help guys. Just one more question would 4.10's be good for 34x10.5x15 LTB's?

4.10's with a DANA 300 and a 4.1 1st gear will work mostly but I find myself wishing I had a t18(or some other 6.1 granny gear sometimes). NVG4500 would be best. Then you could go 4.56 w/a 4.1 DANA 300 and still hit 65 mph

If you ran 4.10 gears, in 4th gear you would need to turn 2400-2500RPM to do 60mph, and about 2600-2700RPM to do 65mph.
