STORY

The Sierra 1500 is GMC's half-ton full-size pickup and the volume model of the Sierra line, sharing its architecture with the Chevrolet Silverado 1500. It has long served as GMC's flagship truck, carrying premium features and the Denali luxury trim that helped establish the brand's upmarket identity. Successive generations have moved from the GMT800 and GMT900 platforms to the K2XX and current T1XX architecture.
