Yukon Inner Axle for Dana 60 99-04 F450 & F550 Superduty Left Hand Side 16.36in Long

This Yukon inner axle shaft is constructed from heavy-duty 4340 chromoly steel, a material known for its high tensile strength and resilience, making it a strong choice for demanding drivetrain applications. It's specifically designed for the Dana 60 front differential found in 1999-2004 Ford F450 and F550 Super Duty trucks, serving as the left-hand side inner axle. This part measures 16.36 inches long and features 35 splines, ensuring a solid connection within the axle housing.

Yukon employs advanced manufacturing techniques to create these axles. The splines are cold roll formed, a process that strengthens the metal without removing material, leading to improved durability and resistance to wear compared to cut splines. Additionally, the axle undergoes advanced induction coil heat treating. This process hardens the surface while maintaining flexibility in the core, which helps prevent breakage under stress and contributes to the axle's overall longevity and performance.

When rebuilding or repairing the front axle on your 1999-2004 F450 or F550, this Yukon inner axle is built to handle the rigors of heavy-duty use. It's designed to work with a 1480 series u-joint, a common and robust size for these trucks. Ensure you have the correct series u-joint for a proper installation.
