Cj-6 Gear ratios

Hey guys I just joined and think is my first thread. So I have a 1971 CJ-6 with the dauntless V6 project I am starting and was wondering if anybody could tell me the gear ratio my jeep has. Thanks any input is appreciated!

 

Do you have a tag on one of the bolts on a differential cover? If so they will show the number of teeth on the ring an pinion gear. Divide the big number by the small number to get the gear ratio.

If you don't see a tag, you can take off the cover and count teeth, or follow the advice from the tech library:

"How do I tell what ratio my axles have?

Jack up rear end, mark drive shaft with chalk, rotate tires 2 full turns while countings number of times the chalk rotates. Unless you have a locker of some sort.

Look for a tag on the differential that has numbers like 43-11, 43/11=3.90 Gears (Example!!!!)

Take the differential cover off and look at the ring gear, it will have the same numbers as the tag stamped on it."

 

My '71 CJ-6 had 4.88s, but yours could also be 3.73s. I doubt it's got 4.27s.
