For Kenworth, the 1950s were some of its most exciting years. A financial windfall started out the decade, with a special truck built for ARAMCO that became a standard at oil sites around the world. In the mid 1950s Kenworth began building trucks in Canada and developed a new design with the cab beside the engine, upping the cargo capacity by 1,000 pounds and offering greatly improved visibility for the driver. In 1956 the company became a subsidiary of the Pacific Car and Foundry Company and under new ownership the 900 model, with a lighter, shorter chassis, was introduced. And, in 1957 the first tilt cab over engine was introduced with easier access to the engine and transmission for servicing.
