4.88 Ring and Pinion Gear Kit

The Zumbrota Drivetrain YGKT005-488-3 is a comprehensive ring and pinion gear kit package, providing both front and rear components along with all necessary installation kits for Toyota 8.4" rear and 8.0" IFS clam-shell front differentials. This kit offers a 4.88 gear ratio, designed to alter the vehicle's final drive ratio for improved performance or to accommodate larger tire sizes. This specific kit is engineered for Toyota 8.4" rear differentials and 8.0" IFS clam-shell front differentials. It is crucial to note that this kit is not compatible with differentials equipped with a factory locker. Additionally, it is designed for front cases that originally accommodate ratios of 3.73 and numerically lower; it will not fit front cases intended for 3.73 and numerically higher ratios. Manufactured by Yukon Gear and Axle, this kit is intended to provide a robust solution for differential upgrades. While the product description does not detail specific installation procedures, differential gear installation typically requires specialized tools and knowledge, and professional installation is often recommended to ensure proper setup and longevity.
