"Take the number of teeth on the ring gear and divide it by the number of teeth on the pinion gear. In this instance of a Dana 44 4.09 gear ratio, there will be 45 teeth on the ring gear and 11 teeth on the pinion gear. 45 divided by 11 equals 4.09 (45/11=4.09) and thus you have a 4.09 ratio"

Thanks! It is indeed a 4.09 or more commonly known as a 4.10 geared Dana 44! I figured it out by spinning the pinion and measuring the amount of turns the ring gear made.

JK7 is a new term to me.
Are those gears different from what comes in the Rubicon?
The Rubicon 4.10 gears are 41 on the ring and 10 on the pinion.
