Ural » 377M

The first prototype of Ural 377 was made in 1961. Despite the successful completion of government tests and launch in series production, it had a number of unavoidable shortcomings associated with the need for unification with the AWD Ural375D.

The result of the work to eliminate these shortcomings was creation of the updated model Ural 377M in 1966-67. It got longer wheelbase (377M — 4620 mm, 377 — 4200 mm) and flatbed platform (377M — 4850 mm, 377 — 4500 mm). Lighter tires OI P46 1100x400-533 were used. Payload was increased to 8 tonnes. Height of flatbed platform was reduced to 1420 mm when engineers decided not to use a spare tire. Curb weight was reduced from 7275 to 6635 kg. Some changes to transmission were made to reduce fuel consumption.

The government test were held since May to November 1967. Two more prototypes were made in December 1967 for strength tests. Future development was stopped in 1969. In December 1968, another two prototypes of Ural 377M were collected. The one used double tires on the rear axles and different front wheels. Tires were O-47A. The second got a fiberglass hood and fenders of the modern design.
