If your steering gets heavy when towing, maneuvering at low speeds, or running larger tires, this pump is built to deliver the extra steering assist your Duramax needs.

These are PSC XD Power Steering Pumps with Performance Pulley for 2001-2010 GMC 2500HD and 3500HD trucks equipped with the 6.6L Duramax and Hydro-Boost brakes, offered as PSC Certified Refurbished units.

Each unit has been inspected, rebuilt where needed, and tested to meet our performance standards. They may show minor cosmetic wear from prior use or handling, but they are fully functional and built to perform the same as our standard units.

The PSC SP1404 is a direct-fit replacement pump designed to provide increased steering performance where it matters most: at low engine speeds and under heavy load. Its high-performance internal design delivers increased low-RPM flow, helping maintain consistent steering assist during parking maneuvers, towing, off-road driving, and other demanding situations.

A stable 1800 PSI pressure relief valve provides the pressure needed to control larger tires while helping prevent unnecessary strain on the steering system.

This pump includes PSC's Performance Pulley, which improves pump speed at lower engine RPM, further enhancing steering response and assist when the engine isn't turning fast enough for a standard setup to perform at its best.

If your factory pump is struggling to keep up or showing signs of wear, this is a cost-effective way to restore steering performance with a pump that's been rebuilt and tested by the PSC team.

All refurbished unit sales are final.
