The Yukon Spin Free Kit replaces the vulnerable & expensive factory unit bearing with standard tapered roller bearings. The tapered roller bearings reduce drag, increasing fuel economy, and are much less expensive to maintain than the factory unit bearings. The kit also adds Yukon Hardcore Locking hubs which provide driving selectability and reduces wear on other components. 4340 Chromoly outer stubs are included with the kit, increasing overall strength of the front end. The end result is a vehicle that drives and handles better, gets better fuel mileage & is more affordable to maintain.
The Yukon Spin Free Kit is a 100% complete kit including all hardware, bearings, seals and small parts for installation. There are no additional parts or products needed or necessary for the upgrade.
