4340 Chromoly Rear Axle

The Yukon Chromoly Rear Axle is a performance-driven component engineered for Ford 8.8” differentials, specifically designed as a replacement for the right-hand side in vehicles equipped with the Yukon Ultimate 88 Kit. Crafted from high-tensile strength 4340 chromoly, this axle benefits from superior production methods, including cold-roll formed splines, and advanced induction coil heat treating to ensure exceptional durability and reliability. This axle measures 28.16 inches in length and features 31 splines, making it a precise fit for its intended application. It is crucial to note that this is not an OEM replacement part. Its design is exclusively for use with the Yukon Ultimate 88 Kit, which modifies the differential by eliminating factory C-clips and increasing the overall axle width by one inch per side. Key specifications include its 4340 chromoly material, 31 spline count, and application for the right-hand side of the rear differential. The specific requirement for the Yukon Ultimate 88 Kit underscores its specialized nature, differentiating it from standard axle replacements.
