Free Up Power And Drive With Confidence

If you're looking for a smarter way to upgrade your front axle, the Yukon YAWU-13 Spin Free Locking Hub Conversion Kit is a serious step up. It replaces the factory unit bearings in your 2012-2017 RAM 2500 or 3500 SRW with serviceable tapered bearings, giving you a more reliable and easier-to-maintain setup. Not only does this reduce your maintenance headaches down the road, but it also helps improve fuel economy by cutting down unnecessary drivetrain drag. You’ll notice smoother cruising and better efficiency, especially on long highway runs. Plus, Yukon includes their low-profile Hardcore locking hubs, so switching between 2WD and 4WD is quick and simple. Whether you're towing, daily driving, or heading off-road, this kit gives your truck more durability where it counts. It's built for drivers who want better performance without compromising reliability.

Engineered For Strength Serviceability And Better Efficiency

The Yukon YAWU-13 Spin Free Kit is designed to eliminate the weak points of factory unit bearings by replacing them with durable tapered bearings and races. This conversion reduces rotational mass at the hubs, which helps boost fuel efficiency by lowering parasitic drag in the drivetrain. Each kit includes high strength 4340 Chrome-Moly outer axles, new wheel hubs, spindles, Timken bearings, quality seals, and all necessary hardware for a complete install. The included Yukon Hardcore locking hubs offer improved reliability and easy engagement when transitioning between drive modes. Fitment is dialed in for 2012-2017 RAM 2500 and 3500 single rear wheel models, but it's important to note that some 2013 and newer OE wheels may not clear the new hub due to smaller inner diameters and non-removable center caps. Yukon’s attention to build quality ensures this upgrade is not only stronger but more serviceable in the long run. It’s a well-rounded solution for truck owners who demand more from their front-end setup.
