Description

The Zumbrota Drivetrain ZGK010 is a comprehensive USA Standard Gear & Install Kit package specifically designed for the Jeep TJ Rubicon. This kit provides the necessary components to upgrade or rebuild the differentials with a 4.88 gear ratio. Included in this package are front and rear ring and pinion sets, as well as master overhaul kits. These kits contain all the essential bearings, seals, gaskets, and hardware required for a complete installation, ensuring proper function and longevity of the drivetrain. The 4.88 gear ratio is ideal for Jeep TJ Rubicon models, especially those equipped with larger tires, offering improved performance and drivability by bringing the engine's RPMs back into an optimal range. This allows for better acceleration and towing capabilities. Zumbrota Drivetrain emphasizes customer support, offering assistance via phone or live chat for any questions regarding fitment or product selection for your build project.
