Construction & Design
The axle kit is crafted from premium 4340 chromoly steel, a material known for its exceptional tensile strength and toughness under extreme conditions. This alloy is a preferred choice in high-performance automotive components due to its ability to resist bending and twisting forces encountered during off-road driving and heavy loads.
Yukon Gear & Axle employs cold roll forming on the splines, a process that enhances the surface finish and increases the strength of the spline teeth by aligning the grain structure. Additionally, the axle undergoes induction coil heat treating, a precise thermal process that hardens the surface while maintaining a tough core, resulting in superior wear resistance and durability.
The double drilled design reduces overall weight without sacrificing structural integrity, contributing to improved vehicle handling and reduced unsprung mass.
Installation & Fitment
This axle kit is engineered as a direct replacement for the right rear axle on select Jeep Gladiator and Wrangler models from 2018 to 2023. It fits vehicles equipped with 2.0L Turbo, 3.0L EcoDiesel, and 3.6L V6 engines. Installation requires standard axle removal and replacement procedures and is compatible with existing axle shafts and differential components designed for 32 spline axles.
No major modifications are necessary, making it a straightforward upgrade for experienced mechanics and off-road enthusiasts alike. Proper installation ensures optimal performance and longevity of the axle assembly.
