Ford Super Duty trucks are built to work—but once you add bigger tires, lockers, or upgraded axles, the factory steering gear starts to show its limits.

These are PSC BIG BORE XD® Cylinder Assist® Steering Gears for 2007.5–2010 Ford F-250 and F-350 Super Duty trucks, offered as PSC Certified Refurbished units.

Each unit has been inspected, rebuilt where needed, and tested to meet our performance standards. They may show minor cosmetic wear from prior use or handling, but they are fully functional and built to perform the same as our standard units.

This gear is designed specifically for Cylinder Assist® systems, built to handle the added load without giving up steering feel or control. It keeps steering tight and predictable when the truck is under stress—whether you're towing, wheeling, or putting it to work.

No wandering, no overcorrection, and no fighting the wheel when things get bound up.

If you're running—or planning—a full assist setup, this is the gear built to handle it.

All refurbished unit sales are final.
