Quick Overview

The OEM steering gearbox in these trucks have always been a problem until now.

The PSC XD-GM steering gearbox features a 45MM sector shaft with an improved roller bearing to prevent sector shaft side-to-side deflection and prevent lower oil seal failure. Larger sector shaft teeth and other internal components have been increased in size to handle the loads that help with larger tire sizes.

Performance Steering Components offers the highest quality power steering gearboxes, pumps, and cylinder assist components for most high-performance power steering applications. Improved component designs ensure superior handling and performance, durability, and reliability for on-the-road, off-the-road, or track.

All PSC power steering components are manufactured from the highest quality materials. From the daily driver to the rock-crawling rig, PSC has the high-performance power steering components you need to make transport a safe, reliable, and enjoyable experience.
