Dorman Products announced the release of a radiator shutter assembly, also known as an active grille shutter. These are fitted for more than 1.5 million Ford trucks. Active grille shutters close to restrict airflow through the grille when the engine doesn’t need to be cooled, routing it around the vehicle, increasing aerodynamics and fuel efficiency. Dorman now has 40 replacements in this category. The need for these items is expected to increase in the coming years as more vehicles are released with this new technology to meet increasingly stringent fuel efficiency standards.
