Jeep Wrangler Spin Free Locking Hub Conversion Kit - Front - Yukon Gear & Axle - Dana 30/Dana 44, 27 Spline, 5 X 4.5, WARN Locking Hubs - `84-`06 is a front hub conversion designed to replace fragile factory unit bearings with serviceable tapered bearings and includes low-profile WARN locking hubs. It fits Jeep TJ/YJ/XJ front Dana 30 and Dana 44 applications with 27 splines and a 5 x 4.5 bolt pattern.

This Yukon Spin Free kit improves serviceability and reduces maintenance cost by replacing one-piece unit bearings with tapered bearings and races. Fewer rotating drivetrain parts reduce parasitic drag, which can improve fuel efficiency. The kit allows straightforward use of a mechanical locker in the front axle without the drivability issues that come from factory unit bearings. Included are new wheel hubs, spindles, high-strength Yukon 4340 chromoly outer axles, premium WARN locking hubs, high-quality bearings and seals, plus all required installation hardware. Note: this kit uses Spicer 5-760X u-joints; some early housings use the smaller 5-260X and may require inner axle changes. Not intended for ZJ or WJ Grand Cherokee, not ABS compatible, and will not work on OE CV-joint applications.
