The gears that were factory-installed in your Jeep are designed to fit the ratio and the torque of the package your vehicle came with. “Gearing” itself refers to the number of teeth in your ring and pinion gears, and this number is a measurement of how many times your driveshaft has to rotate in order to spin your wheels once. Driveshafts connect to the axle shafts on pinion gears. When your drive shaft rotates, the pinion gear spins the ring gears which, in turn, spin your axle shafts, making your vehicle move.
