1955 - GMC introduced both new styling and a new engine for its 1955 "Second Series" lineup of pickup trucks. As the first major redesign since 1947, the new '55 GMC featured a two-bar-grille format, hooded headlights, bumper with circular guards and stylized GMC lettering mounted on the lower hood surface. The 287-cubic-inch, 155-horsepower engine marked the introduction of V8s for light-duty GMC trucks. GMC also offered a new and very stylish pickup model with fiberglass bed and special trim. Called the Suburban Carrier, this rarely seen GMC was a sibling to Chevrolet's new Cameo Carrier pickup. 1956 - GMC offered factory-installed, NAPCO-supplied 4WD. 1957 - Minor grill changes. 1958 - Very few changes to the truck line, with a new grill and dual headlights. After producing only a few hundred Suburban Carriers, GMC changed mid-year to the new Fleetside bed - the fleetside tailgate is used all the way to '66. 1959 - This is the last year of the "Task Force" trucks. GMC introduced the All New Aluminum "Tilt Cab Cruiser" with a 48" BBC, a true cab over engine truck. It came with or without a set back front axle. GMC Tested an all new V-6 Truck engine, the 305.
