PSC Performance BIG BORE XD Steering Gear Box

If you’re tired of sloppy steering or fighting big tires on your Super Duty or Excursion, PSC’s BIG BORE XD Steering Gear is the upgrade you’ve been waiting for. This isn’t a rebuilt box—it’s a completely new design built from the ground up to handle serious off-road and towing demands.

The SG752 features a larger sector shaft and beefed-up internal bearings for smoother steering and better durability. It works with factory and aftermarket pitman arms, and it’s a direct bolt-in for 1999–2005 Ford trucks and SUVs.

Need more turning power? Go with the Cylinder Assist® Ready version (SG752R). It’s ported to work with PSC’s Cylinder Assist system, giving you the torque to turn big tires with ease—even when your diffs are locked.
