Description

The Yukon Chromoly Rear Axle is engineered for demanding applications, specifically designed for use with the Ultimate 88 Kit on Ford 8.8” differentials. This left-hand side axle shaft is crafted from high-tensile strength 4340 chromoly, ensuring superior strength and longevity for off-road or high-performance use. Utilizing advanced production methods, this axle features cold roll formed splines and induction coil heat treating. These processes contribute to an axle of unmatched quality and durability, capable of withstanding significant stress. With 31 splines and a length of 31.16 inches, it is specifically designed to work in conjunction with the Ultimate 88 Kit, which modifies the factory differential by eliminating C-clips and increasing axle width by one inch per side. It is important to note that this is not an OEM replacement part and requires the Ultimate 88 Kit for proper installation and function.
