GMT800
The GMT800 and similar GMT880 is the basis for the current Chevrolet Silverado pickup truck. The derived GMT820 and GMT830 is used in the Suburban, among other large SUVs.
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 GMT800 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]
Applications:
- GMT800/880
- GMT820/830

The updated GMT900 will debut at the 2006 North American International Auto Show. The first GMT900 vehicle will be the next-generation Cadillac Escalade. The GMT900 series will feature standard vehicle stability control and will offer American Axle's "I-Ride" independent suspension module. GMT900 production will begin at GM's Janesville, Wisconsin plant in late 2005.
