Show original supplier description

The Yukon Minor install kit is a comprehensive solution for performing ring and pinion gear changes on Dana Spicer 70HD and Super-70 differentials, particularly when the original bearings are still in good condition and can be reused. This kit offers a cost-effective approach to differential maintenance and upgrades. Specifically, you will find a pinion seal to prevent leaks, a complete shim kit for precise gear backlash adjustment, and marking compound with an accompanying brush for proper gear pattern analysis. These components ensure that the differential is installed correctly for optimal performance and longevity. The product is manufactured by Yukon Gear and Axle, a reputable brand in the drivetrain industry. It is designed to fit the Dana Spicer 70HD and Super-70 axle models.
