PSC Performance Duramax XD Power Steering Pump Kit. The heart of any modern power steering system is the pump. PSC offers a full range of new power steering pumps, covering most applications.

This High Performance Series pump kit is built for GMC 2500 and 3500 trucks running the 6.6L Duramax from 1999–2010. It’s a strong, direct‑fit upgrade that gives your steering system more flow at lower RPM and the pressure needed to turn larger tires, especially on trucks with Hydro‑Boost brakes.

PSC builds this pump with a larger ring and rotor for improved output, includes a premium high‑pressure hose kit, and pairs everything with our 715 performance power steering fluid. It installs cleanly, works with the factory pulley, and delivers the kind of consistent assist a Duramax truck should have.
