Description

The Yukon Chromoly Outer Front Axle is engineered for robust performance in Chrysler 9.25” differentials. Constructed from heavy-duty 4340 chromoly, this axle offers superior strength and longevity for demanding applications. This axle features a 35-spline count and a length of 7.4 inches, specifically designed as a front outer axle. It is compatible with 1550 Series u-joints, ensuring a secure and reliable connection. The use of high-tensile strength 4340 chromoly, combined with cold roll formed splines and advanced heat treating, results in an axle of unmatched quality and durability. For 2013-2018 applications, this axle can be used with the additional purchase of axle nut # YSPSP-019. This technical note is crucial for ensuring proper fitment and function in those specific model years.
