Construction & Design:

The axle shafts are crafted from premium 4340 chromoly steel, known for its exceptional tensile strength and fatigue resistance. Yukon Gear & Axle employs cold roll forming for the splines, a process that enhances the spline geometry and surface finish, resulting in superior fitment and longevity. The shafts undergo an advanced induction coil heat treating process, which hardens the steel to resist wear and bending under extreme loads.

The wide track design at 33.1 inches increases the vehicle’s track width, improving stability and handling characteristics, especially during off-road maneuvers. This robust construction ensures the axle kit can handle the increased stresses of lifted or heavily loaded Gladiators.

Installation requires standard axle replacement procedures and may involve professional alignment to ensure optimal performance. The kit includes all necessary hardware such as wheel bearings, seals, studs, and lug nuts to facilitate a smooth installation process.

No significant modifications are typically needed, making it a straightforward upgrade for Gladiator owners seeking enhanced axle strength and reliability.
