What is Professional Grade? It's a commitment to a higher standard of innovative engineering, design, and performance. It's not more than you need. It's just more than you're used to.
For more than 100 years GMC has dedicated it'self to understanding what people expect in a truck, and then worked to exceed those expectations every step of the way. So when you call on your Sierra to give you more, you can have confidence that it will do virtually whatever you ask of it.
