GMT 355
The GMT 355 is the redesigned S/T compact pickup truck design and the successor to the GMT 325 series. GMT 355s are built in Shreveport, Louisiana and Rayong, Thailand. GMT 355 uses an A-arm independent suspension in front and live axle with leaf springs in the rear. The Atlas straight-4 and straight-5 engines are widely used, starting in 2009, a 5.3L V8 was added. A 4-speed automatic and 5-speed manual transmission are also specified.
The GMT 355 platform was actually a joint-venture with Isuzu, though most of the design was done by Isuzu. Part of the agreement was that GM had to sell it first in the U.S., to be sold legally as an Isuzu. Despite its close numbering to the GMT 360 series, the two programs share nothing.
GMT 355 Applications:
- Chevrolet Colorado (Most markets until 2013 model year; North America until 2014)
- GMC Canyon
- Holden Rodeo
- Isuzu D-Max (Isuzu i-Series)
- Hummer H3
GMT 360
The GMT 360 debuted in 2002 with the Chevrolet TrailBlazer, GMC Envoy, and Oldsmobile Bravada, as the next generation S/T mid-size SUVs. 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. In the rear, the Ascender and TrailBlazer use a 5-link rear suspension, while the rest have an air suspension. A 4-speed automatic is the only transmission available.
Prior to GM's 2009 bankruptcy, all GMT 360 products were discontinued and the Moraine, Ohio plant that produced the GMT 360 series was closed. Simultaneous with the cancellation of the GMT 360 program, development of the GMT 361 replacements were also suspended. A new body-on-frame midsize SUV retaining the Chevrolet TrailBlazer name and built in Thailand was launched as part of the GMT 700 program; however, it will not be sold in North America, as the GM Lambda platform crossovers fill the market's need.

GMT 510

They would have complemented the GMT 960 series, which are Lambda sport wagons. Due to poor sales of all U-Body vans, this series has been cancelled.
GMT 530/560
The GMT 530 series of trucks are medium-duty commercial trucks, such as the 1990-2002 Chevrolet Kodiak and GMC Topkick. The GMT 560 platform is the one of the 2003-2009 Kodiack/Topkick trucks.

GMT K2XX
Also known as the "Next Generation Full-Size Pickup" and "Next Generation Full-Size SUV" platform within General Motors, the GMT K2XX is the replacement for the GMT 900 series. The K2XX platforms went into production in the summer of 2013.
The first GMT K2XX vehicles were light-duty 2014 model year Chevrolet Silverado and GMC Sierra full-size pickups. The 2015 Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon, GMC Yukon XL, Cadillac Escalade, and Cadillac Escalade ESV full-size SUVs followed, then the 2015 Chevrolet Silverado HD and GMC Sierra HD. Concurrent with the switch from GMT 900 to GMT K2XX, the Chevrolet Avalanche and Cadillac Escalade EXT were no longer produced. Hybrid versions of the Silverado, Sierra, and full-size SUVs were also discontinued. However, fuel economy of GMT K2XX vehicles increased over the GMT 900 predecessors thanks to usage of new Generation V/EcoTec3 V8 engines with direct injection and weight savings from the use of more high-strength steel. Turbocharged and diesel engines for light-duty models are also under consideration for future GMT K2XX trucks and SUVs.
Four plants build GMT K2XX products: Arlington Assembly (all SUVs), Flint Truck Assembly (double and crew cab heavy-duty pickups), and Fort Wayne Assembly (regular and double cab light- and heavy-duty pickups) in the United States, along with Silao Assembly in Mexico (crew cab light duty pickups). The first GMT K2XX vehicles produced were light-duty crew cabs built at Silao Assembly, followed shortly afterwards by light-duty regular and double cabs built at Fort Wayne Assembly.
