Part Number: SD-SP1404-PG

mmThe PSC SP1404 is a direct-fit power steering pump built to deliver more steering assist where you actually use it—down low and under load. Designed specifically for 6.6L Duramax engines equipped with hydro-boost brakes, this pump provides increased low-RPM flow and a stable 1800 PSI pressure relief to help handle larger tires without overworking the system.

This unit is offered as a PSC Certified Refurbished pump. Each pump has been inspected, rebuilt where needed, and tested to meet our performance standards. It may show minor cosmetic wear from prior use or handling, but it’s fully functional and built to perform as intended.

If your stock pump struggles to keep up once you’ve added tire and weight, this is a solid upgrade that keeps steering consistent and predictable—especially when you’re working the truck at low speeds.

All refurbished unit sales are final.
