This material is not a KrAZ company history, is just a chronology of 6x6 vehicles YaAZ/KrAZ, created for the army, started in the former Soviet Union and continued after the collapse of the Soviet Union.
The history of this vehicle, began in 1956, in Yaroslavl, Russia, on the YaAZ factory; (YaAZ - Yaroslavsky Avtomobilny Zavod). Developed on a project since 1951, the plant YaAZ want to made a 6x6 vehicle for the army, to replace the 6x4 models, YaAZ 210G, with payload of 8 tons, used during that period. The project launched in 1951, called YaAZ 214, was based on YaAZ 210 model, was similar in architecture with 210 series, but with transfer case modified to admit the installation of a driving axles in front.
The transfer case of model YaAZ 210, was with 2 speeds, lockable symmetrically interaxial differential and independent outputs for each rear axle. On this model, the two driving shafts, runs parallel, from the transfer case to first rear axle: the right driving shaft drive the reducer of the first axle, the left driving shaft drive the driving shaft of the second axle through a coupling mounted on the first rear axle. The vehicle was equipped with an axle with single wheels in front, two rear axles with twin wheels and tires: 12.00-20. Length: 9660 mm, or: 7375 mm (210G), width: 2650 mm, wheelbase: 5050 mm + 1400 mm, or: 4780 mm + 1400 mm (210G), track front / rear: 1950 mm / 1920 mm.

YaAZ 210G
Prototype YaAZ 214 was equipped with 2-stroke diesel engine with 6 cylinders in line, YaAZ-206, similar to U.S. GMC 6-71 engine, with engine capacity: 6981 cc, power: 165 hp, torque: 70.5 daNm, wooden cabin, covered with tin, twin disc dry clutch, 5-speeds gearbox and transfer case with 2 speeds, without central differential between front axle and rear axles, with lockable symmetrically interaxial differential and independent outputs for each rear axle, the intermediate shaft of the transfer case, drive along with the rear axles differential, the axis of the front driving shaft. This shaft was provided with the possibility of decoupling the front transmission, the vehicle running under normal conditions, only with rear wheels drive. The vehicle was equipped with an axle with single wheels in front, two rear axles with twin wheels and tires: 12.00-20. Length: 9660 mm, width: 2650 mm, wheelbase: 5050 mm + 1400 mm, track front / rear: 1950 mm / 1920 mm.
YaAZ 214 prototype
In 1956, the YaAZ factory decided to introduce in production a new military vehicle with payload of 7 tons, with all-wheels drive, equipped with single wheels and equally track. The new prototype taken the technical platform of the YaAZ 214 of 1951, and its name. The new YaAZ 214 chassis was shorter, had a new wooden cabin, covered with tin and straight front grill (cabin that will equiped all series YaAZ 6x4 - 219, 221, 222 and YaAZ 6x6 - 214), was equipped with new engine 2-stroke diesel, 6 cylinders in line, YaAZ-M206B, displacement: 6981 cc, power: 205 hp, torque: 78 daNm, steering with pneumatic booster, twin disc dry clutch, 5 speeds gearbox and transfer case with 2 speeds, without central differential between front axle and rear axles, with lockable symmetrically interaxial differential and independent outputs for each rear axle, mechanical winch, tires : 15.00-21. Length: 8530 mm, width: 2700 mm, wheelbase: 4600 mm + 1400 mm, track front / rear: 2030 mm.
In 1957, the factory has developed a project for a new range of trucks, including a military 6x6 model called YaAZ 230. This project has never materialized.
In May 1958, the Soviet government developed a plan for reshaping the factories and decided to move the trucks production to Kremenchuk, in Ukraine, to the KrAZ factory; (KrAZ - Kremenchuksky Avtomobilny Zavod), YaAZ following to specialize in engines production, thus ending YaAZ trucks production. Subsequently, the name of the factory became YaMZ; (YaMZ - Yaroslavsky Motorny Zavod).
