USA Standard Gear 35095 4340 Chromoly Outer Stub Axle Shaft Dana 60/70 35-Spline 12"

The USA Standard Gear 35095 (ZA W46100) is a 4340 chromoly replacement outer stub axle shaft designed for Dana 60 and Dana 70 front differentials. Featuring a 35-spline count and measuring 12 inches from the end of the splines to the center of the u-joint bore, this outer stub is engineered to deliver a direct-fit, high-strength upgrade over factory axle components.

Factory axle shafts are typically manufactured from 1040 alloy steel, whereas this USA Standard Gear shaft is machined from high-tensile 4340 chromoly alloy steel — a material upgrade that provides significant gains in torsional strength and resistance to bending under load. Advanced heat-treating processes are applied to further enhance durability and fatigue resistance.

On a front axle assembly, the outer stub shaft connects the universal joint to the hub assembly, transmitting drivetrain power through the steering knuckle while allowing for articulation. This shaft is compatible with needle bearing u-joints only (such as the Spicer 5-332X style). It is engineered to meet or exceed OEM specifications and is a direct replacement for worn or broken factory stubs.
