Trials began during the same year. It is being proposed for military and civil applications. Since the 1970s KrAZ was developing 8-axle high mobility chassis. There were a number of prototypes but these never reached production. The resulting KrAZ-7634NE was built in small numbers for Ukrainian military needs. First KrAZ-7634NE was delivered to Ukrainian military in 2019. These vehicles are used to carry radars and missiles. Though exact production numbers were not disclosed.

   This vehicle is fitted with a Chinese Hubei RDGD forward control cab, which is used on Chinese commercial vehicles. It accommodates driver and co-driver. It can be also fitted with a Ukrainian armored cab which provides protection for the crew against small arms fire and artillery shell splinters.

   Vehicle was initially proposed with a Russian YaMZ-7511.10 turbocharged diesel engine, developing 400 hp. There was also a version powered by a 420 hp engine. Interestingly vehicle delivered to Ukrainian military in 2019 was powered by a different YaMZ-7511 engine developing 460 hp. Developers claim that this vehicle can be fitted with other engines, including Ford and Deutz engines, developing 400-500 hp. Engine is located behind and under the cab.
