High Performance Power Steering Pump 2001-2010 GM Duramax with Hydroboost Braking System PSC Performance Steering Components
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 1800 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.
