Yukon Gear 4340 Chrome-Moly Blank Axle For Dana 60 42in Long

Starting with a 1.578-inch diameter and 42-inch length, this Yukon Gear 4340 chromoly blank axle is built for serious drivetrain work. It’s designed for Dana 60 differentials, offering a solid foundation for custom builds or replacements where precise spline engagement is critical. The 4340 chromoly material provides a strong core, ready to handle the demands of off-road or heavy-duty applications.

Yukon uses advanced induction coil heat treating on these axles, a process that hardens the surface while maintaining flexibility in the core. This helps prevent breakage under stress. They also employ cold roll forming for the splines, a method that strengthens the metal at the spline roots, which is a common failure point on lesser axles. Because this is a blank axle, it means you or your shop can cut custom splines to perfectly match your differential and hub setup, ensuring a precise fit and optimal power transfer.

This axle is intended for the inner position and is not splined from the factory, giving you the flexibility to machine it to your exact specifications. It's designed to work with a 5-332x U-joint, a common size for heavy-duty applications. If you're building a custom drivetrain or replacing a worn axle in a Dana 60, this Yukon blank axle offers a well-built starting point.
