How will reinforcing the springs add load carrying capacity? How could it not. Whenever a mechanical part is strengthened it gains better ability to do it's job. Swapping heavier duty springs, axles, tires, wheels, etc. onto a truck will in fact increase the ability of the truck to carry weight. It's just a machine and conforms to the laws of physics.
No, it won't change the sticker on the door. Lets say I have a 3500 truck with an 11,000 pound GVWR. My driver's door gets dented and I go to the junk yard and get a door from a 1500 truck to replace it. Now the door sticker's GVWR number is 7,500. I'm I know restricted to a GVWR of 7,500 with my 3500 truck because of what the sticker says?
Reinforcing the springs will not add capacity because the springs aren't the only thing needed to support the load. Putting fancy springs on your truck does not increase the tire rating, make the frame stronger, or make it stop any faster.
The sticker on the door is the manufacturer's rated capacity for that truck. And no, changing the door, changing the sticker, or removing the sticker won't change the facts.
Your state might have lax laws but not all do.
