2001-2005 Max-Flow High Performance Water Pump Kit (MAX-HPWP-0105)

Built for high RPM and high horsepower use, though it works just as well on a stock 2001-2005 Duramax. When you lift off the throttle at high RPM, cooling system pressure can crack or spin the heavy factory cast impeller on its shaft; this kit swaps in a much lighter resin impeller that reduces inertia and is far less likely to spin. Comes with everything needed for install as a direct bolt-on replacement.
