Yukon Gear Spin Free Locking Hub Conversion Kit For 07-18 Jeep Wrangler JK 5 x 5.5in Bolt Pattern

Yukon Gear & Axle is known for making strong drivetrain components, and their Spin Free Locking Hub Conversion Kit is a prime example of that commitment. If you're looking to improve your 2007-2017 Jeep Wrangler JK's fuel economy and simplify maintenance, this kit is designed to do just that. It swaps out the factory unit bearings, which can be prone to failure and costly to replace, for a more robust system using tapered bearings and races.

By reducing the number of rotating parts in your drivetrain, this kit cuts down on parasitic drag. This means less power is wasted, leading to noticeable improvements in your gas mileage. Plus, the tapered bearing design makes servicing much more straightforward and economical down the road. This kit also comes with low-profile Yukon Hardcore Premium Locking Hubs, allowing you to quickly switch between two-wheel and four-wheel drive when you need it.

Included in this comprehensive kit are heavy-duty 4340 chromoly outer axles with 30 splines, front double-drilled rotors, and the Dana 44 Yukon Hardcore Locking Hubs. While the rear rotors are sold separately, this kit contains all the other necessary components to complete the conversion. The 7166 u-joint size is also specified for this application, ensuring a proper fit for your Jeep Wrangler JK.
