Jeep XJ Axle Kit - Front - Yukon Gear & Axle - 4340 Chromoly & Grizzly Locker ('84-'06) is a complete front Dana 30 axle upgrade for 1984–2006 XJ Jeeps. This kit pairs heavy-duty chromoly shafts with a Yukon Grizzly locker and the components needed for a robust off-road setup.

Manufactured from high-tensile 4340 chromoly, these axles feature cold roll formed splines and advanced induction heat treating for increased strength and durability. The kit includes 30-spline inner and 27-spline outer shafts, Yukon Super Joints, carrier bearings and races, a vacuum disconnect block-off kit, and necessary hardware. The Yukon Grizzly locker fits gear ratios 3.73 and up to deliver dependable traction where you need it most.
