The second-generation Dyna was released in April 1963. Unlike its predecessor that had shared the frame with the Stout bonnet-type truck, the second-generation model adopted a newly developed original frame. Other prominent features included a 3.1-meter long bed, four headlamps, and a wide windshield. A long body version was added to the lineup in October 1963, with the wheelbase and bed extended by 625 mm and 1,000 mm, respectively. Although the second-generation Dyna started with a 1.9-liter 80 hp gasoline engine (3R-B), a 2.3-liter diesel engine (Type J) was also made available in March 1964 to fend off fierce competition from the Isuzu Elf diesel (released in September 1960), leading to a great success of Dyna in the truck market.
