PSC SP1404 P-Pump, GM Trucks (96-10), V8 6.6L Duramax, M16-1.5 F HP 3/8in Tube Return, Hydro-Boost

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.
