Rear Bumper Options

Thursday, February 11th, 2010

Ever wonder why GM pickup rear bumpers have been an option for so many years?


Beginning in 1951 these bumpers became an extra cost option and have remained this way ever since on most pickup models.

The reason relates to trucks being mostly for work. Though protecting the bed from minor rear damage, a bumper also kept the driver from backing up against a loading dock. GM found that many farmers and construction workers had been removing the rear bumper to get the truck flush against a dock. This eliminated most of the gap between the truck and dock. Broken legs of livestock and employees during loading were also greatly reduced.

The following picture is an example of a 1955 and newer GM step bed pickup. Its owner went against the current trend of adding the optional rear bumper during its restoration and kept his truck basic. It is important to note, that to protect the license plate bracket without a bumper, GM placed it on the left side. Holes are in the middle of the rear cross sill from the factory to make it easier for the dealer to install the rear center license plate bracket while adding the optional bumper.

Note the rear spare tire arm is at an angle to also protect it from damage if backing or being even lightly bumped in traffic.

This picture shows an optional right taillight. From the assembly line this truck would have only the left light with attached license bracket.

Accessories vs Options

Thursday, February 11th, 2010

As per GM, accessories during the 1930’s through mid 1960’s were the extra cost items sold and installed by the approved dealer. The truck was prepared for these during production so the dealership could later add them with less effort.

As much as possible GM would punch holes, attach removable plates, press in dimples, etc. to help the dealership in placing the accessory in just the right position. Several accessories using the pre-placed holes or dimples in these early Chevrolet and GMC trucks are the right side taillight bracket, fresh air heater, radio, front bumper guards, cigarette lighter, arm rest, glovebox light, and windshield washer.

Options were added at the factory. They were more difficult to install by individual dealerships and were therefore placed on the vehicle during production. This included items such as a chrome grille, 4 speed transmission on 1/2 and 3/4 ton chassis, double action shocks, tinted windows on 1953-55, two speed rear axle on larger trucks, double action fuel pump, hydrovac power brake, etc.
