In 1940 the production of the well known 10-ton series NR (6x6) was started. It was created using the chassis EXBX. These trucks were used for long hauls of large military units, different loads and towing heavy artillery. The trucks were equipped with a line 6-cylinder diesel ED (8,5 l, 123-131 hp) with direct injection, Laova system cylinder head, dry single plate clutch, 10-speed Mack Duplex transmission with two reverse gears, double main gear, front 24-inch wheels and rear with tires size 14.00-20. By the end of the War the company Mack had built 16,548 trucks of the NR series (from NR1 to NR20), which also were supplied to the USSR under the lend-lease. The models were differed by types of bodies, one or double rear wheels and a purpose. The first trucks had closed all-metal cab, but in 1942 the trucks received soft-top cabs. The variants: NR1 - version with an angled cab as the model EXBX. NR4 - with closed cab of a new type with rounded forms (then all NR trucks had such cabs) with payload of 13 tons. It was used to transport the light tanks M3. NR6 and NR7 used to tow various artillery units.
