Max-Flow High Performance Water Pump Kit 2001-05 Silverado Sierra 6.6L Duramax

Max-Flow High Performance LB7 LLY 6.6L Duramax Water Pump Kit. The Max-Flow High Performance Water Pump kit is designed specifically for high RPM and high horsepower applications but is also a great replacement for stock applications as well. When the engine is seeing high RPM's and you suddenly let off the throttle, the pressure in the cooling system can cause factory style pumps to fail.

The heavy factory cast style impeller will usually break or spin on the shaft. We have even seen welded water pumps fail as well.

This Max-Flow High Performance Water Pump comes with a lightweight resin impeller that can handle high RPM's and is a direct bolt-on replacement. This complete kit comes with everything you will need to install the water pump.
