This BIG BORE XD Cylinder Assist steering gear is built for Ford Super Duty trucks that work hard and carry weight on the front end. Designed for 2011–2025 F‑250 and F‑350 trucks, it starts with a heavy‑duty Ford‑based gearbox and adds PSC’s larger internal bore for stronger, more controlled steering when running larger tires.

Prepped and ready for Cylinder Assist, this gear delivers improved steering response, reduced wheel fight, and better control under load—whether the truck is towing, plowing, or spending time off pavement. It bolts in cleanly and holds up to real‑world use without changing the feel of the truck where it matters.

Heads‑up for installers

  • Gear is prepped for Cylinder Assist plumbing
  • Welding required for hydraulic spuds
  • Proper system bleeding is critical for best steering feel
  • Core charge applies to the steering gear
