Cylinder Assist Steering Gear Box for 6.7L Powerstroke

If your steering’s starting to feel loose or unpredictable—especially after lifting your truck or adding larger tires—you’re not imagining things. The factory gearbox on the 2011–2024 F250 and F350 6.7L Powerstroke just isn’t built to handle the extra strain that comes with serious off-road use or heavier setups. That’s where the PSC Cylinder Assist Steering Gear Box comes in. It’s more than just a replacement—this is a serious upgrade designed to restore tight, confident steering while giving you the foundation to support future mods.

Built with brand New Components

At the heart of this unit is PSC’s Big Bore XD design, which uses all-new components—no re-manufactured internals here. The sector shaft has been upsized to better handle the higher torque loads that come with off-road driving and oversized tires. That larger shaft, paired with upgraded bearings, delivers a noticeably smoother and more responsive feel behind the wheel. It helps eliminate the vague, wandering sensation that so often shows up as these trucks age or see heavy use. What really sets this version apart is its built-in Cylinder Assist compatibility. If you’re planning to install a PSC Hydraulic Assist kit down the line, this gearbox is ready to support it right out of the box. That means less hassle later and one less component to swap when you’re ready to go full tilt on your steering upgrades.
