Western Star Trucks owes its appearance in 1967 to the American corporation White Motor Company, which decided to expand the scale of its production by organizing another branch.
And the founding father of the newly formed division was Semon Emil Knudsen, the son of William Signius Knudsen, a well-known specialist in the North American automotive industry.
Production of heavy-duty lightweight trucks that met the weight standards (axle loads) in force in the western states of the United States.
Their production was launched in the city of Ogden, Utah. Hence the name Western Star.
Newly made trucks received the designation White-Western Star. The main product line was the hood models of the 4800 and 4900 truck series (4x2 and 6x4), and a little later - the 4700.
Like a number of other American manufacturers, Western Star took over the production of frames, cabs, suspension components, and general truck assembly.
Everything else was supplied by third-party specialized firms.
The trucks were equipped exclusively with diesel engines (usually Caterpillar) with power from 175 to 380 hp, mechanical 10-13-speed gearboxes, larger radiators and separate sleeping compartments for mainline tractors located behind the cab.
As intended, the trucks produced in Ogden differed from the basic White 4000 trucks family by the most lightweight design.
For the sake of this, the spars and cross members of the frame, radiators, fuel tanks, wheel disks, bumper, parts of the cab and crankcases of some units were made of aluminum, and the integral plumage that combined the hood and wings was made of fiberglass.
Western Star trucks quickly managed to gain a foothold in the North American market, and its products found recognition among consumers.
The machines were constantly improved, their production grew, the number of modifications increased, including off-road models with single wheels.
The scope of the use of trucks has also expanded. They successfully mastered mining, logging, housing and communal services, etc.
The style of trucks has also changed.
Rounded shapes gave way to more faceted outlines.
The exterior of the trucks was characterized by wide rectangular radiators, an abundance of chrome for exterior trim, and natural lacquered wood and high-quality leather were used in the interior, especially when it came to "long-range" tractors.
The aggregate base has also expanded.
Detroir Diesel and Cummins diesels appeared in the configuration, the choice of transmissions increased. The impressive range of the wheelbase made it possible to mount various superstructures.
