The 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 1650 PSI pressure relief to help handle larger tires without overworking the system.
It bolts right in, reuses the factory pulley, and keeps an OEM-style look with a matching reservoir and cap. The result is predictable steering feel, solid brake assist, and a no-nonsense upgrade that just works.
