Question: what is the difference between a dodge 3500 and 4500?
Answer: A 3500 looks just like a 4500/5500 when parked side to side but the frame of the bigger trucks is slightly thicker metal and they have slightly taller frame rails on the class 4 and 5. The heavier trucks have 19. 5" wheels/tires, larger brakes, much larger and stiffer springs, and a 76 mph speed governor.
