Jeep YJ Axle Kit - Front - Yukon Gear & Axle - 4340 Chromoly + Grizzly Locker - `84-`06. This front axle kit combines 4340 chromoly axle shafts with a Yukon Grizzly locker to upgrade Dana 30-equipped Jeep YJ/TJ/XJ/ZJ models from 1984–2006. It provides a robust, serviceable package for serious off-road use.

Yukon high-performance axles are manufactured from high-tensile 4340 chromoly and use cold roll formed splines and advanced heat treating for strength and durability. This kit is built to replace factory shafts and add a selectable locking differential solution; it includes inner and outer chromoly axles, carrier bearings and races, hardware and 1310-series U-joints. The Grizzly locker provided fits gear ratios 3.73 and up and the vacuum disconnect block-off kit simplifies installation on Dana 30 fronts.
