The Dodge D400 was a one-and-a-half-ton, four-wheel drive pickup truck. The D400 had strengthened suspension and support systems compared to the D300, but shared the same V8 engines. The D400 was also available with 225 slant-6 and 361 V8 engines. The vehicle was part of Dodge's third generation D-Series of rear-wheel drive pickups. The D400 had three-speed automatic transmission and had options of power assisted brakes and cruise control.
