Yukon Gear Spin Free Locking Hub Conversion Kit For 12-15 Dodge 2500/3500 - YA WU-13

Yukon Gear & Axle Spin Free Kits increase fuel efficiency and reduce maintenance costs. These 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. Less parasitic drag equals better MPG. Spin Free Kits also include low-profile Yukon Hardcore Premium Locking Hubs, for quick changes between two-wheel and four-wheel drive.

May not fit OE wheels for 2013+ models. Design changes to some factory wheels eliminated the removable center caps and step down the ID of the wheel, not allowing it to clear the wheel hub.
