Description

A must have upgrade for your Duramax puller! This fixed fan hub will eliminate your OE viscous fan clutch and increase your intercooler efficiency. Early testing shows considerable decreases in intake air temps and coolant temps, both of which equate to more power. Testing, fitment trials and data collections are happening as we speak and will become available as they are validated.
