Yukon Spin Free Kits landing page
Yukon Gear & Axle Spin Free Kits replace the failure prone and expensive factory unit bearings with tapered bearings and races. The result is not only a design which is easier and more economical to service, but one that offers significant increases in fuel efficiency because there are fewer rotating parts in the drivetrain for the engine to spin. Less work equals more mpg. These hub kits also include low-profile Yukon Hardcore premium locking hubs, for quick changes between two-wheel and four-wheel drive.
Each kit includes new wheel hubs, spindles, high strength Yukon 4340 chromoly outer axles, Yukon Hardcore premium locking hubs, Timken bearings, high-quality seals, and all hardware for installation. Kits are accompanied by a limited lifetime warranty against manufacturing defects for as long as you own the vehicle.

Gear tooth patterns are harbingers… they can foretell whether your ring and pinion gear set is going to live a long and prosperous life or if it’s doomed to an impending catastrophic failure. Pulling off a proper differential setup comes down to precise adjustments. Parameters like pinion depth, backlash, pinion-bearing preload, and carrier-bearing preload allow you to fine tune the relationship between gear teeth to ensure proper meshing and ultimate durability.
