*Sold as is with no returns

*Parts have been opened, but are new and unused

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.
