One of the easiest and most effective ways to improve the performance of any off-road vehicle is to upgrade the Jeep YJ ring and pinion gears. The system that is installed in the rear-drive differential gearbox is responsible for transferring power from the driveshaft to the axles and then to the wheels of your vehicle. Because most of the torque loading occurs at the gearing change, a stronger, more appropriate ring and pinion set can reduce wear and tear on the drivetrain. Not only should the entire system last a lot longer, but performance should also be improved over the life of the vehicle. The only downside is that pinion gear sets can be a chore to install. Even do-it-yourselfers would be well advised to leave this project to the professionals. That said, you can still save money if you purchase these sets from us and have your local mechanic do the work.
