DHD 500-112 High Performance High RPM LB7 & LLY Duramax Water Pump

Dirty Hooker Diesel 500-112 High Performance High RPM Water Pump LB7 LLY Duramax

With the advancements in technology and tuning, these Duramax diesels are producing more horsepower and torque than originally intended and thus the water pump suffers. We have come up with a solution to the problematic water pump on the 2001-2005 LB7 & LLY Duramax Diesels. Our water pump does not utilize the heavy cast water pump wheel, but a light weight resin wheel. We modify the covers and bracket in order to bolt right in place of the existing pump. Everything is included with the pump in order to install.
