Description
If you’ve got a 2005–2007 Ford F-250/F-350 Super Duty and the steering feels like it’s wrestling you back — especially with big tires or heavy loads — this kit’s your answer. The BIG BORE XD Cylinder Assist Steering Kit is PSC’s top-tier solution for trucks that need serious steering help.
This setup includes our XD Steering Gear with a beefed-up sector shaft, a bolt-on Cylinder Assist system to help move those oversized tires without beating up your gear, and a full supply of PSC 715 fluid to keep everything running smooth. It’s built for real trucks that work hard and play harder — not for mall crawlers.
