Shortly after WWII the Chevrolet Truck Division introduced a heavier truck with a maximum gross weight of 16,000 pounds and was rated as a 2 ton. Up to this time their top rated truck had been 1 ½ tons with a gross weight of 14,000 pounds.
With this increase, a major change occurred in the front bumper. No longer was this bumper little more than a heavy duty ½ ton. They now used a totally different design. A top and bottom horizontal ridge and additional thickness did much to prevent bending when pushing another vehicle or by an accident.
The 1 ½ and 2 ton bumper, introduced in 1946 was not continued through the next series of trucks, 1947 through 1953. The next series no longer had the bolt heads in the middle. Now the bumper center extended out (even wider) and the recessed bolt heads were on the top and bottom. This gave more pushing surface without damage to the bolts.
