Outer Axle Shaft Dana 70

The Dana 70 Outer Axle Shaft (Part Number 3-82-871) is a heavy-duty OEM replacement component engineered for front axle assemblies requiring maximum load capacity and durability. Manufactured by Dana-Spicer, this outer axle shaft features a 35-spline design and measures 12 inches in length, making it the proper fit for Dana 70 differentials in demanding off-road, commercial, and recovery applications where stock axle performance is critical.

The 35-spline count provides a larger contact surface between the shaft and differential, distributing torque more evenly than finer spline counts and reducing shear stress under extreme loads. Steel construction with a natural finish resists corrosion in typical operating environments while maintaining the structural integrity required for heavy towing, rock crawling, and expedition use. At 8.22 pounds, this is a precision-engineered component designed to OEM specifications rather than an aftermarket approximation, ensuring proper fitment and long-term reliability.

This Dana 70 axle shaft replacement is essential for vehicle owners restoring damaged front differentials, addressing wear in high-mileage axle assemblies, or upgrading to heavier Dana 70 housings for increased load capacity. Serious off-road enthusiasts, commercial fleet operators, and restoration specialists rely on OEM Dana-Spicer components to maintain the engineering standards and longevity that factory assemblies are designed to deliver.
