Jeep TJ Axle Kit - Front - Yukon Gear & Axle - 4340 Chromoly & Grizzly Locker - `84-`06 is a complete front Dana 30 axle kit built for serious off-road use. It combines Yukon 4340 chromoly axle shafts with a Grizzly locker and Yukon Super Joints for improved strength and traction in demanding conditions.

This kit is engineered with high-tensile 4340 chromoly and cold-rolled splines plus advanced induction heat treating to increase durability under load. Designed for Dana 30 front applications on compatible Jeep models from 1984–2006 (TJ/XJ/YJ/ZJ platforms), the package includes inner and outer axles, a Grizzly locker (fits 3.73 ratio and up), Yukon Super Joints, a vacuum disconnect block-off kit, and necessary bearings, races and hardware. The result is a ready-to-install assembly intended for trail use, heavy-duty applications and customization projects. Note: Super Joints require more maintenance and are generally not recommended for daily-driven vehicles.
