The GMT800 is the basis for the previous generation Chevrolet Silverado full-size pickup truck. The derived GMT820 and GMT830 is used in the Suburban, among other full-size SUVs. This is the successor to the GMT400 series of C/K pickups and SUVs, and was replaced for 2007 by the new GMT900 line.

It uses three boxed-in hydroformed sections rather than a single long frame. This gives greater flexibility to the platform. A total of four front modules, seven midsections, and four rear sections were created to mix and match for nearly 40 different truck configurations.

The GMT 800 platform was introduced in 1999. Frames are manufactured by Magna International in Ramos Arizpe, Coahuila, Mexico and St. Thomas, Ontario, Canada. Final assembly is in Oshawa, Ontario, Pontiac, Michigan and Fort Wayne, Indiana. The GMT820-based Hummer H2 is built under contract by AM General at a specially-constructed plant in Mishawaka, Indiana, USA.^[1]
