Meet the New Mid-1955 GMC Truck

Tuesday, February 4th, 2020

With the introduction of the new 1955 GMC Blue Chip trucks. (Chevrolet used the name “Task Force.”) The GMC Truck Division made their statement with changes that were different in many ways than their Chevy competitor. Much of the sheet metal was identical to Chevrolet but there was just enough changes that allowed them to be a market and stand alone!

The new 1955 GMC trucks sometimes had their own independent dealers but more often their pickup line was marketed by GM car dealers such as Pontiac or Buick.

The stepside pickup beds were almost identical to Chevrolet but the tailgate displayed the famous GMC logo. (A nice advertising touch to show the follower, the pickup in front was a pure GMC.) To standout even more, the hood, grill, hubcaps and dash were much different than Chevrolet. The seat springs and frame were the same but the appearance of the cloth and vinyl gave a different appearance. Even the 6 cylinder and V-8 engines were different than Chevy! The GMC Truck Division would say “Our pickups are certainly a step above the competition.”

Engines:

Through the transmissions, differentials, and brake systems were mostly the same as the Chevrolet, their engines were very different. It appears that GMC would not share this most important part from their competition.

The 1955 six cylinder was 270 cubic inch. This was the same engine that had been optional in their first series 1955 trucks. (One of GMC’s greatest in the engine category.)
In regards to a V-8 engine it appears GMC was not prepared when they discovered Chevrolet had developed a small V-8 engine. (Yes, GM had a V-8 but it was 2 very large unit used in off road equipment and commercial highway vehicles. Too large for ½ to 2 ton trucks.)

Now what? GMC did what they had done in 1938 with a similar situation. The borrowed Pontiac’s engine! They could now boast, they had the largest V-8 in a pickup truck.
