Although around as a trim level option for numerous years, it wasn't until 1998 when the GMC Sierra became a permanent full-size offering. Based on the same GMT800 platform as the Chevy Silverado, the GMC Sierra showcases a lot of the same top-quality characteristics. What separates the two trucks besides badges is that the Sierra features luxury options. The light-duty GMC Sierra is the 1500 and is available in a 2-door short cab, 3- or 4-door extended cab, and front-hinged 4-door crew cab. Bed lengths come in three different choices: short box (69.2"), standard (78.7"), and long (97.6"). The first generation of the Sierra is also rear-wheel drive with 4-wheel drive as an option. In 1999, a redesign saw the addition of Quadrasteer as the 4-wheel drive system for both trucks, and upgrade of some of the GMC Sierra parts and components. The grille was changed and new interior trim was employed, as well. The first year of the Sierra saw only the regular cab and the 3-door extended cab as available. Engine options included a 3.3L Vortec 4300 V6, a 4.8L Vortec 4800 V8, and a 5.3L Vortec 5300 V8.
The Sierra HD is the heavy-duty version of the truck. It is available as the Sierra 1500HD, 2500HD, and 3500HD. 2001 is when the 1500HD was made available. Equipped with a 6.0L Vortec 6000 V8 with the capability to crank out 300 horsepower, the entry-level Sierra HD packed enough punch to generate some interest. It was also mated to a Hydra-Matic 4-speed transmission. The GMC Sierra 2500HD arrived with even more pop. A Duramax V8 (360HP) and 650 lbs. per foot of torque was offered as was a Vortec 8100 V8 with slightly less horsepower (340). Either engine option includes a 5-speed Allison 1000 transmission (6-speed for 2006-07). The GMC Sierra 3500HD uses the same engines and transmission as the 2500HD. What makes the 3500HD different are the twin rear wheels and stiffer suspension. Sierra HD trucks are usually preferred for construction, towing, and for those who regularly transport a substantial amount of cargo. The 1500HD features approximately 10,300 for its towing capacity with the 2500HD rated at 16,100 pounds and the 3500 at 16,700 pounds, respectively.
In 2006, the GMC Sierra and the Chevy Silverado were moved to the GMT900 platform for the 2007 model year. The redesign included changes to the exterior GMC Sierra parts, such as a more aerodynamically shaped body, a refined grille, reinforced suspension, and more powerful engine options. The engine configurations are different for the GMT900 Sierra, as well. A Generation IV small block V8 engine is used along with Active Fuel Management, which shuts down half the cylinders in order to conserve fuel. All versions of the truck run on a 4-speed automatic transmission with 6-speed automatic transmissions expected to take over permanently. When 2008 rolled around, GM full-size trucks no longer became available with a manual transmission in Canada and the US. The Sierra also comes with two different dash choices, depending on the driver's preference. One is a dash that is more luxury-oriented and shares the same traits as those found in the GMT900 SUVs. A "pickup" dash that displays more upright angles is also offered for more room in the cabin.
The GMC Sierra crams a mix of authoritative presence, big-time toughness, and smooth performance into one big, stylish package. The Sierra has been molded out of the successful GM platform that also spawned Chevy's revered Silverado, and both share many of the same traits. The Sierra allows for a comfy in the cab which hosts all of the modern amenities normally reserved for high-end sedans. Backed by conscientious handling and unbridled power, the GMC Sierra is one lion that knows how to prowl.
