In 1957 the DCOF-405 high tilt cab 6x4 tractor replaced the International DCF-405 non-tilting COE. The new cab was based on the Diamond T cab of the CO-180 to CO-220 series, but mounted much higher to clear big-bore diesel engines and the required big radiator. The DCOF-405 used big 743 ci Cummins engines ranging from the 165-hp HRB-600 to the 335-hp turbocharged NRTO-6B. In 1958 the 180-hp 672ci NH-180 was made standard. In 1959 the DCOF-405 was restyled slightly with new dual headlights (reverting to singles later). In mid-1961 it gained several new engine choices. Cummins replaced the 335-hp 743 ci NRTO-6 with the 335-hp 855 ci NT-335.At the same time 2-cycle Detroit Diesels were made available in the series: the 218-hp 6-cylinder 6-71N, the 218-hp V6 6V-71N, and the 290-hp V8 8V-71N. Also newly available were two International-built engines, the 250-hp naturally-aspirated D-817 and the 375-hp turbocharged DT-817. In addition to the dual-drive DCOF-405 International made the trailing-axle tandem DCOT-405 and the lightweight versions DCOF-405L, with Cummins mid-range diesel, and VCOF-405L with International V8 gasoline engines.
