4.88 Ratio Ring and Pinion Gear Set

The Yukon Gear & Axle high-performance ring and pinion gear set is designed as a direct replacement for Dana 30 axles. This set offers a 4.88 gear ratio, providing an optimized performance upgrade for vehicles with larger tires or increased horsepower. The set is engineered with a 7.20" ring gear diameter, 26 spline pinion, and requires 10 ring gear bolts and 10 cover bolts for installation. Yukon engineers employ state-of-the-art design principles, advanced heat-treating techniques, and rigorous quality testing processes. This ensures the structural integrity and surface finish of the gears meet stringent automotive standards. The result is a durable and reliable gear set that performs to expectations. This specific gear set is designed for standard rotation Dana Spicer 30 differentials that do not use a crush sleeve. Yukon also offers a comprehensive, lifetime Y.E.S. Plan warranty, providing no-questions-asked protection for the gear set as long as you own the vehicle, subject to certain restrictions.
