PSC STEERING BOX

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.
