The International K and KB series are trucks that were produced by International Harvester, the first being the K introduced in 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 K models progress from 1 to 14 based upon the load capacity (K1 = half ton, K2 = 3/4 ton, K3 = 1 ton, etc.).
There are no K-9 or K-13 model trucks.
