Its all in your preference.

By the way, what year is your Jeep? Not all years had 3.73s, and no, it wasn't a standard option on Saharas. Origianlly, 3.08s were the only gears, even with 30" tires.

97s had 3.55s as an option. In 97 jeeps (2 years production), 3.73s were only available with the 4 cyl automatic models. 6 cyls had 3.08s or 3.55s only.

Post up what year your Jeep is, what your present tire size is, and what your RPM is at some speed in some gear (like 2500 rpm @ 75 mph in 5th gear)

If you take a wire brush and clean the front diff cover, you might find the stamp. My TJs had the gear ratio punched directly into the axle cover, not on the old standard tags.

My personal experience: I had two TJs both with 3.73 gears and 31s. Both could have used 4.11s in my opinion. For 33s, I'd have run 4.56s.

My TJ was ordered with 3.73 gears(dana 44) and 27" tires. There is no mileage difference between the two.

People are afraid to spin their engines.

But, if you don't feel like putting gears in it, then just toss on the tires and run it. If you have 3.73s you'll be able to use 5th gear, if you have 3.08s, you won't. At least in inclines or headwinds.
