In 1941 the KR-11, with double-reduction rear axle, replaced the previous International DR-70. The International KS-11 was the same basic truck but with a 2-speed rear axle. These K-11 series trucks were International's top-of-the-line gasoline-powered conventional-cab 4-wheelers in the early-1940s and through the war years. They sold very well and were possibly the most common big tractors on the road at the time. The K-11 series began with a 27,000 lb GVW rating, a 114-hp International FBC-401 6-cylinder engine, 5-speed transmission, and standard air brakes. A few trucks were built as KRD-11 and KSD-11 models with 150-hp Cummins HB-600 6-cylinder diesel engines. In 1944 the small number of civilian trucks the government allowed to be built were KR-11-450 and KS-11-450 models fitted with the new 134-hp Red Diamond RED-450 engine. In 1945 the regular KR-11 had a 140-hp RED-401 engine and the KR-11-450 had an upgraded 148-hp RED-450. With full civilian production in 1946 the 148-hp engine was made standard in the KR/KS-11.
