Technical Details and Construction

The Dorman 630-434 drive axle shaft assembly is manufactured from high-quality carbon steel, providing the necessary strength to withstand the stresses of heavy-duty use in Ford Super Duty trucks and Excursion SUVs. The assembly features a Dana 60 differential case design, which is common in these vehicles, ensuring compatibility and reliable performance. With 35 inboard splines and 30 outboard splines, the axle shaft offers secure engagement with the differential and wheel hub. The 8x170 wheel bolt pattern size matches the factory specifications for these models, while the 1.58-inch shaft diameter supports effective torque transfer. This assembly does not include wheel studs, ABS tone rings, brake hardware, or seals, so those components must be sourced separately if needed.
