Jeep Model 20 Final Drive Gears - Yukon Gear & Axle - Ring & Pinion 3.31 Ratio - `68-`06. This Yukon ring and pinion set is a direct-fit option for Model 20 differentials, providing a 3.31 final drive ratio for drivers updating gearing to match drivetrain changes.

Built by Yukon Gear & Axle, this set uses high-grade steel and advanced heat-treating plus a refined tooth surface finish to reduce friction and heat under load. Engineered and tested in Yukon’s quality labs to meet OEM fitment and performance standards, the 3.31 ratio is suitable for vehicles with increased horsepower or larger tires where a change in final drive is required. The design aims for quiet operation when properly installed and adjusted. Yukon includes a one-year manufacturer warranty and offers the optional Y.E.S. Plan for lifetime coverage of the gear set.
