Yukon Dana 60/70/80 Full Float Rear Axle – 35 Spline, Chromoly, Cut to Fit
YUKYA WFF35-36.5
The Yukon Chromoly Full Float Rear Axle Shaft is built for heavy-duty Dana 60, Dana 70, and Dana 80 rear axle applications that demand maximum strength and reliability. Manufactured from high-tensile 4340 chromoly steel, this axle shaft is designed to handle large tires, towing, off-road abuse, and high-horsepower applications that push factory shafts beyond their limits. Its cut-to-fit design allows builders to customize axle length for narrowed housings, fabricated rear ends, and custom-width axle builds.
Built using advanced heat-treating and manufacturing processes, this 35 spline axle shaft provides exceptional fatigue resistance and spline durability under extreme load. Whether you're building a tow rig, mud truck, Ultra4-style race vehicle, or hardcore crawler, this full float axle shaft is engineered for dependable performance in demanding environments.

Tech Insight
4340 chromoly axle shafts are widely used in high-load off-road and towing applications due to their superior tensile strength and resistance to twisting under torque. Full float axle designs further improve durability by allowing the hub assembly—not the axle shaft itself—to carry vehicle weight.
Cut-to-fit axle shafts are commonly used in custom fabricated housings and narrowed axle applications where factory shaft lengths are no longer suitable. Proper spline engagement and accurate cutting are critical for long-term durability and safe operation.
