Yukon GM 14-Bolt 10.5"/11.5" Rear Axle Shaft – Chromoly , Cut to Length
YUKYA WGM14T-30-35
The Yukon Chromoly Full Float Rear Axle Shaft is built for GM 10.5" and 11.5" 14 bolt rear axles that demand increased strength and reliability under heavy load. Manufactured from high-tensile 4340 chromoly steel, this axle shaft is engineered to handle larger tires, towing, off-road abuse, and high-horsepower applications that can quickly overwhelm factory axle shafts. Its cut-to-length design provides flexibility for custom axle widths and fabricated housing applications.
Yukon uses advanced manufacturing methods including cold roll formed splines and induction heat treating to improve fatigue resistance and long-term durability. This results in a stronger spline structure and more consistent material strength throughout the shaft. Whether you're building a rock crawler, tow rig, Ultra4-style race vehicle, or heavy-duty truck, this axle shaft is designed to provide dependable performance in extreme conditions.

Tech Insight
4340 chromoly axle shafts are a major upgrade over standard alloy or factory shafts due to their improved tensile strength and fatigue resistance. Cold rolled splines further improve durability by compressing the grain structure rather than cutting material away like traditional machining processes.
Cut-to-length axle shafts are commonly used in custom fabricated housings and narrowed axle builds, allowing builders to create exact-fit axle lengths for custom track widths and suspension configurations.
