CUCVs of all generations are still in U.S. service, though many M880/M890s and CUCVs have passed through military surplus sales into civilian ownership. They had a Military rated top speed of 70 mph (110 km/h). Most were equipped with the Loadflite 727 3-speed automatic transmission, though a few left the factory with a 4-speed manual. The trucks were equipped with front disc brakes and rear drum brakes.
