Description

This specific set is designed for Dana 30 reverse rotation differentials and comes with a 3.73 gear ratio, making it suitable for optimizing traction performance or accommodating upgrades such as larger tires or increased horsepower. Key specifications for this Yukon ring and pinion set include a 7.20-inch ring gear diameter, a 26-spline pinion, and provisions for 10 ring gear bolts. It is explicitly designed to fit Dana Spicer 30 differentials that do not utilize a crush sleeve. The high-performance nature of these gears ensures they meet exacting specifications and quality standards through leading-edge testing processes. Yukon Gear and Axle offers a comprehensive Y.E.S. Plan, a lifetime, no-questions-asked protection plan that covers the gear set for any failure, for any reason, as long as you own the vehicle. This provides added assurance for your drivetrain investment.
