Designed as a direct-fit left-side rear axle, this shaft delivers a significant upgrade over factory components for drivers who demand greater strength and reliability.

Yukon performance axle shafts are manufactured from 4340 chromoly steel, a high-tensile-strength alloy renowned for its superior toughness and resistance to torsional stress. Each shaft undergoes cold roll formed spline processing, which work-hardens the spline teeth for increased fatigue resistance compared to cut splines. An advanced multi-stage heat treatment process further optimizes hardness and core toughness throughout the shaft, resulting in a part built to withstand the demands of off-road and high-performance use.
