1967-1974 GM Pickup/Suburban Power Steering Gear Box (ZSG7501)

Description

The USA Standard Gear ZSG7501 is a high-performance, brand-new power steering gear box engineered to restore precision and responsiveness to classic truck steering systems. Unlike remanufactured units that may retain worn internal housings, this gear box is manufactured with 100% new components to eliminate common steering issues such as "vague" center feel, lane drifting, and steering wheel play. It is designed to meet or exceed original equipment specifications, providing a reliable solution for heavy-duty applications.

This unit features a precision-machined internal valve body and high-strength gearing to ensure smooth, consistent torque through the entire steering range. Designed for a direct bolt-on installation, the ZSG7501 integrates seamlessly with factory mounting points and hydraulic lines, significantly reducing installation time while improving overall vehicle handling and safety.
