Overview
The GMC Sierra HD Chassis Cab is for buyers needing more than a factory bed. Think dump truck, flatbed, utility box, or whatever else contractors, construction workers, and other commercial needs require. It comes as a normal cab, but then there's no box on the back. Just a bare chassis and the world is your oyster.
What’s New/Key Changes From Last Year
Just a year old, there are no significant mechanical or appearance changes.
