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 (also part of the S/T family) series, the two programs share nothing.
