This ensures long-lasting performance in demanding driveline environments. The seal features a counter-clockwise spiral lip design that improves sealing efficiency by directing contaminants away from the shaft interface. Its flanged outside diameter of 3.425 inches (87 mm) and housing bore of 3.161 inches (80.3 mm) provide a secure fit within the differential housing, while the shaft diameter of 1.874 inches (47.6 mm) matches the pinion shaft specifications of compatible Ford Super Duty models.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cp\u003eThis differential pinion seal is specifically compatible with Ford F-250 Super Duty and F-350 Super Duty trucks.
