Ford Super Duty trucks are tough, but once you throw on bigger tires, lockers, or upgraded axles, the stock steering gear starts to feel outmatched. That’s where PSC’s Big Bore XD Cylinder Assist setup comes in — built to handle the extra load without giving up road feel or drivability. This gear keeps your steering tight and predictable, whether you're hauling, wheeling, or just heading to work. No wandering, no oversteer, and no need to muscle the wheel every time you turn.
