When upgrading the factory-size tires on the Rubicon 392, the next step for most is an axle gear ratio change or even an entire axle swap for axles spec'd to handle the force and power the platform can provide to the newly installed larger tires. Whether it is a gear change to get back lost power, upgraded axle shafts that are stronger than factory, or an entire axle swap to one-ton truck axles that are designed to bolt right in; RubiTrux has multiple offerings to fit your build needs.
