Yukon Dana 60/70 Chromoly Front Outer Axle Shaft - 35-Spline
YA W46100
The Yukon Dana 60/70 35-Spline 4340 Chromoly Front Outer Axle Shaft is built for heavy-duty front axles that need more strength than a standard factory replacement shaft. Made from high-strength 4340 chromoly steel, this 12" outer stub shaft is designed to handle the torque and shock loads created by oversized tires, locking differentials, high-horsepower engines, and aggressive off-road driving. It's a practical upgrade for Dana 60 and Dana 70 front axle builds where steering joints and outer axle shafts take a beating on the trail.
Yukon uses cold roll-formed splines and induction heat treatment to improve spline durability and fatigue resistance under load. This 35-spline front outer shaft is designed for compatible Dana 60 and Dana 70 front axle assemblies using a 5-332X-series U-joint configuration. Whether you're rebuilding a factory one-ton front axle or putting together a custom rock crawler, the important part is matching the outer shaft to the inner axle shaft, U-joint, wheel-end assembly, and overall axle configuration.
Includes:
- (1) Yukon 4340 Chromoly Front Outer Axle Shaft - 35-Spline
Important: This listing includes one front outer axle shaft only. The inner axle shaft, U-joint, and other axle assembly components are not listed as included. Verify shaft length, spline count, U-joint compatibility, and wheel-end configuration before ordering.

Fitment Notes:
- Designed for compatible Dana 60 and Dana 70 front axle assemblies
- 35-spline outer axle shaft configuration
- 12" overall shaft length
- Compatible with the specified 5-332X-series U-joint configuration
- Front outer stub shaft only; inner axle shaft sold separately
- Verify axle shaft spline count, length, and U-joint compatibility
- Confirm wheel hub, spindle, and outer wheel-end configuration before ordering
- Factory axle configurations may vary by year and vehicle application
- Professional installation and inspection of related axle components are recommended
Builder Note: When upgrading a Dana 60 or Dana 70 front axle, the outer stub shaft, inner shaft, U-joint, and wheel-end components must work together. A stronger outer shaft does not correct worn U-joints, damaged splines, or incompatible wheel-end parts.
FAQ
What is the advantage of a 4340 chromoly outer axle shaft?
4340 chromoly steel is a high-strength alloy commonly used in performance drivetrain components because of its toughness and fatigue resistance. Compared with many factory-style outer shafts, a properly manufactured 4340 shaft is better suited for the shock loads created by larger tires, locking differentials, and aggressive off-road driving.
Will this axle shaft fit my Dana 60 front axle?
It is designed for compatible Dana 60 front axle assemblies using a 35-spline outer stub shaft, 12" shaft length, and matching U-joint configuration. Not every Dana 60 uses the same outer shaft, so verify the installed axle and wheel-end dimensions before ordering.
Does this listing include the inner and outer axle shafts?
No. This listing includes one front outer axle shaft only. The matching inner axle shaft and U-joint are separate components and must be selected for the complete axle assembly.
What U-joint works with this outer axle shaft?
This Yukon outer axle shaft is specified for a 5-332X-series U-joint configuration. Confirm that the matching inner shaft uses the same joint dimensions and that the complete assembly is compatible before installation.
What is the benefit of cold roll-formed splines?
Cold roll-forming shapes the splines by displacing material rather than cutting it away. This process can improve fatigue resistance around the spline roots, where axle shafts experience high torsional loads during hard acceleration, rock crawling, and drivetrain shock.
Can this shaft be used with a locking differential?
Yes, when installed in a compatible front axle assembly. A locking differential increases the traction available at both wheels, which can also increase loads on the axle shafts and U-joints. Matching the complete axle assembly is important for reliability.
Is this outer axle shaft sold individually?
Yes. This listing includes one 4340 chromoly front outer stub shaft. Two outer shafts are typically required for a complete front axle, one for each wheel end.
What should I inspect when replacing an outer axle shaft?
Inspect the inner axle shaft, U-joint, spindle, wheel hub, bearings, seals, and related steering components. Verify that the U-joint fits correctly and that the shaft moves through the required steering range without binding before returning the vehicle to service.
