The GMT 360 debuted in 2002 with the Chevrolet TrailBlazer, GMC Envoy, and Oldsmobile Bravada, as the next generation S/T mid-size SUV's. While it replaced the GMT 330, it shared nothing with the older platform. It used hydroformed frame rails like the larger GMT 800, and was built for GM's Atlas inline engines. The GMT 360 (and the long-wheelbase GMT 370) went on to be one of the most rebadged GM products with six different marques represented.The 360 uses an independent suspension in front.
