Show me a truck that IS rated to tow 4 times its own weight.
Any DRW 3500 that's rated to tow 30k+ is pushing 10k empty these days. I'm talking about the bare truck fresh off the dealer lot. Puts you down in the mid 3's.
Now I'm going to blow your point clean out of the water: The only thing limiting a Class 8 truck is THE LAW. 80K is a legal limit. The truck is capable of far more. You can get overweight permits and tow at 102K gross easy. That gets you solidly into the "3's" with your Class 8 truck strawman. Far more is possible, all you need to do is pull the permit and have enough axles on the ground.
The Class 8 truck will do 4-5 times its own weight all day every day with a smile. A DRW 3500 at 4 times is going to start showing fatigue and wear quite early in its life.

Also, I know class 8 trucks because I have worked in the heavy duty industry for over 20 years and my point being is that it is not always hard parts that limit a trucks actual capacities. Like class 8 is limited by laws and regulations, so is class 2b that most 2500 trucks are in that the OP was asking about. And also just like class 8 trucks, you can register a 3/4 ton to be able to carry more than the class 2b limit of 10k GVWR, but I would have to pay double the registration. Manufactures will continue to make class 2b HD trucks because fleets demand them so they don't have to pay added taxes/registration along with limited CDL requirements once you get past 10k GVWR(Class 3 and up).
So it is not the actual hard parts that is limiting 2500's these days. It is laws and regulations of class 2b trucks just like the laws and regulations that limit class 8 trucks.
And no, you will need a special truck to tow 4-5 times the weight. These are called heavy haul spec'ed trucks and they are heavier than your regular on highway tractor with a GCW of 80k due to the added pusher axles and other beefier components. We made a lot of these heavy haul trucks when I worked for Peterbilt/Kenworth, and also made engine for them when I worked at Cummins. Now we sell them at my current company.
