4.88 Ring and Pinion Gear Set

The Yukon Gear & Install Kit, model YGK006, is a comprehensive package for upgrading the differentials on a Jeep TJ equipped with Dana Spicer 30 front and AMC Model 35 rear axles. This kit is specifically designed for a 4.88 gear ratio, providing enhanced performance for off-road applications or larger tire sizes. This kit includes both front and rear ring and pinion sets, ensuring a matched upgrade for your vehicle's drivetrain. Additionally, it comes with master overhaul kits, which contain all the necessary bearings, seals, and installation hardware for a complete and proper installation. The components are manufactured by Yukon Gear and Axle, known for their quality in drivetrain parts. Compatibility and installation notes are crucial for this kit. While the kit is designed for a 4.88 ratio, customers currently running a 3.54 ratio will need to purchase a new front carrier separately to ensure proper function. Similarly, vehicles running a 3.07 ratio will require the purchase of both new front and rear carriers in addition to this kit. It is highly recommended to consult with Zumbrota Drivetrain's tech support or a professional installer if you have any questions regarding fitment or the technical notes provided.
