Not any more. The Ford 6R140 is also used in class 6-8 F670/F750 trucks. Most people think that just because the F750 has a 7 in it then it is a class 7 only. However, some variants of the F750 have GVWR's above 33,001 lbs which makes them a class 8 heavy duty truck.
Professional truckers would laugh at you for calling an F750 a Class 8, even if it does require that level of a CDL !
And let them, it still doesn't mean they are right. There are more trucks in the Class 8 category than just line haul trucks.
Many consumers think that the number on the door is what places a truck in a certain class, but in the medium/heavy duty industry those numbers are practically useless and are just names of that that particular model. It is the actual specs and capabilities that count, not the badge number or name.
Take Peterbilt trucks for instance. Their line haul trucks(or what you would constitute as a real class 8) have model designation of 579 and 389. Does this mean that the 579 is a class 5 and the 389 is a class 3? No, it is just a model name or number and has nothing to do with the class it is in or it's capabilities. It is only the people outside the industry who would think this.
Just like an early 2000's SRW 350/3500's were actually Class 2B trucks just like the 2500's going by their specs and ratings. Yet, people will still call them a "1-ton" or say they are a class 3 truck just because it has a "3" in its name.
