International Harvester K and KB Series
Encyclopedia
The K and KB trucks were produced by the International Harvester Company, the first being the K introduced in the mid 1940. In total there were 42 models, 142 different wheelbase lengths and load ratings ranging from 1/2 ton to 90,000 lbs. They are best known for their durability, prewar design in a postwar era, and low price. The followup to the K, the KB, was introduced in 1947, with the characteristic difference being a widened lower grill appearing like "wings". Between 1947 and 1949 122,000 KB-1 and KB-2 trucks were sold. The KB series was subsequently replaced by the L-Series

Models
The K models progress from 1 to 8 based upon the load capacity (K1 = half ton, K2 = 3/4 ton, K3 = 1 ton, etc).Light duty
Few differences exist between K-1 and K-2 models as they share most of their mechanical and chassis components. The rear axles in these two models is supported by a single roller bearing. Their differences in load rating are due to the K-2's stronger suspension.The K-3 has a heavier frame, larger brakes, and rear axles supported by two roller bearings on a free floating rear end.
Styling
The style of the truck involved headlamps that were integrated into the fenders. The hood opens alligator style. Heavy duty models (K6 and above) carried over the D-series cab and high crowned fenders.
