Yukon Gear Spin Free Locking Hub Conversion Kit For Dana 30/Dana 44 TJ/XJ/YJ 27 Spline/5 X 4.5

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 steel hubs for quick changes between two-wheel and four-wheel drive.
