History
Although General Motors introduced its first pickup truck in 1930, the term "Silverado" was a designation used only to detail the trim for the Chevrolet C/K pickup trucks and Suburbans from 1975 through 1999. GMC used a few variations of the "Sierra" name (Sierra, High Sierra, Sierra Grande, Sierra Classic) to distinguish the different trim levels through 1987, though the "C/K" nomenclature was continued through 1999. "C" (or "R" for 1987) trucks were rear-wheel drive and "K" (or "V" in 1987) models were four-wheel drive. The "R/V" nomenclature was continued from 1988-1991 to distinguish the older platform trucks that were still being produced in addition to the T400 platform C/K. Both Chevrolet and GMC dropped the "C" and "K" designations in 1999. However Chevrolet still uses the CK and the CC in their current model codes.
The Chevrolet Silverado and GMC Sierra trucks have been essentially the same for their entire history. The Silverado today is generally advertised as the "standard" version and is more aimed for use in agriculture, while the Sierra is aimed for industrial workers but can be ordered as a well equipped luxury truck. There are some trim and option variations as well. Early models included variations in the engine and equipment, but the present differences are slight. The 1999 redesign included different grilles and interior trim, and certain features (e.g. Quadrasteer) were included at different times on the two trucks. Chevrolet did not create a Denali model for the Silverado. However, the GMC Sierra has a Denali model.

The GMT800 Silverado/Sierra 1500 (light pickup trucks) were released in 1998 as 1999 models. The "classic" light-duty GMT400 C/K trucks were continued in production for that first year alongside the new models, and the Heavy-Duty GMT400 pickups (alongside the GMT400 SUVs) were continued through 2000, with the new GMT800 Silverado/Sierra HD (Heavy Duty) introduced in 2001. A small refresh was introduced in 2003, bringing slight design changes and an upgrade to the audio and HVAC controls.
Light duty
There are a number of models of light-duty Silverados and Sierras, including the half-ton, SS, and Hybrid.
The light-duty trucks generally use the 1500 name. They are available in three cab lengths, 2-door standard/regular cab, 4-door extended cab, and front-hinged 4-door crew cab Three cargo beds are available, including a 69.2 in (1,758 mm) short box, 78.7 in (1,999 mm) standard box, and a 97.6 in (2,479 mm) long box. The short box is only available with the extended or crew cab, and is the only option on the latter. The new trucks used a new hydro-formed technology on the frame which GM pioneered from the corvette and was designed to add strength and take away mass and was later used by ford and ram.
For the first year, only the regular cab and 3-door extended cab were available, along with the Vortec 4300 V6, Vortec 4800 V8, and the Vortec 5300 V8. A 4-door extended cab was added for 2000, and output on the 5.3 L engine increased to 285 hp (213 kW) and 325 lb·ft (441 N·m).
The 6.0 L Vortec 6000 V8 was added for the 2001 Heavy Duty models, rated at 300 hp (224 kW), with the GMC Sierra 1500 C3 getting an uprated 25 hp (19 kW) version of this engine. The Silverado Z71 got an optional lighter composite box, with a suspension package for towing, but lacked the high-output engine. The C3 became the Denali for 2002, and Quadrasteer was added.
GM made a reworked version of the Silverado/Sierra in 2003, with a new front end, and a slightly updated rear end. Its SUV counterparts retained the use of the pre-facelift sheetmetal.
The Insurance Institute for Highway Safety (IIHS) gave the Silverado an overall "marginal" score on the frontal offset crash test for poor structural integrity and poor dummy control, although no injuries were recorded on the dummy's body regions.
2001 GMC Sierra C3/Denali
GMC created an upscale version of its Sierra 1500 in 2001 called the Sierra C3. It used all-wheel drive with a 3.73 final drive gear ratio and included the 6.0 L Vortec 6000 LQ4 V8 rated at 325 hp (242 kW) at 5000 rpm and 370 lb•ft (502 N·m) of torque at 4000 rpm coupled to a 4L60E-HD four speed automatic transmission along with other upscale equipment. For 2002, the name was changed to Sierra Denali, but the specifications remained essentially the same except for the addition of Quadrasteer and GM changed from the 4L60E-HD to the 4L65E in conjunction with a 4.10 final drive gear ratio.
The Denali is rated for towing 9,100 pounds (4,100 kg) and hauling 1,595 pounds (723 kg) in the cargo box.
The Sierra Denali was initially equipped with Delphi's Quadrasteer system as standard equipment. It was a 4-wheel steering system that greatly reduced the truck's turning radius and improved lane changing while towing. General Motors dropped Quadrasteer from the Sierra Denali after the 2004 model year and its entire lineup after 2005 due to poor sales of this expensive option.
For the '07 model year, the Sierra Denali shares the same billet grille from the other Denali models, and also has the same dash as the '07 SUV's. The '07 Sierra Denali was initially the only half ton pickup that had a 6.2 liter with 403 hp (301 kW) and 417 lb·ft (565 N·m) of torque coupled to a six speed transmission. This truck is also an optional all wheel drive vehicle and goes 0-60 mph in 6.3 seconds.
Chevrolet Silverado SS
Launched in 2003, the Silverado SS is a high-performance pickup truck built by Chevrolet. It is based on the 1500 Silverado with upgrades in drive train and both exterior and interior appearance. It was equipped standard with the 6.0 liter Vortec High-Output V8 rated at 345 hp (257 kW) at 5200 rpm and 380 lb·ft (515 N·m) of torque at 4000 rpm coupled to a 4L65E four speed automatic transmission. This was the same engine used for the second generation Cadillac Escalade. Chevrolet and GMC advertised this engine as the Vortec High Output and later as the "VortecMAX", while Cadillac calls it the "HO 6000". The SS debuted in 2003 with a standard All Wheel Drive setup with a 4.10 final drive gear ratio and 4 wheel disc brakes. In 2005 as an option to reduce the price, you could get a 2 wheel drive version which was equipped with drum rear brakes and a 3.73 final drive gear ratio. 2005 was also the first year the sun roof was available in the SS line up. In 2006 The AWD line up was dropped and rear wheel drive with a 3.73 final drive gear ratio and rear drum brakes was the only option. In a further effort to reduce cost, you could also get cloth interior and a bench seat for the first time. The Silverado SS also comes with the Z60 performance suspension and 20 inch aluminum wheels. All the SS trucks in both 2 wheel drive and AWD used the torsion bar style front suspension for better handling. It should also be noted the SS themed trucks were only available from the factory in Black Onyx, Victory Red, and Arrival Blue Metallic in 2003 and 2004. In 2005 Arrival Blue Metallic was dropped from the color choice and replaced with Silver Birch Metallic.
Vortec High Output/Vortec Max
The Vortec High Output option (also known as the VHO by some enthusiasts) was first introduced in 2004 to a limited market (mainly consisting of Texas and several surrounding areas). The VHO package (under option code B4V) included several options previously not found on the standard 1500 model, most notably the LQ9 6.0 L V-8 engine (the same used for the Silverado SS, the 2005-2006 GMC Denalis and the Cadillac Escalade). The LQ9 motor was rated at 345 hp (257 kW) at 5200 rpm and 380 lb·ft (515 N·m) of torque at 4000 rpm, which was the same specifications shared in the SS models. The B4V package could only be ordered as an extended cab in 2004 and 2005. They were all built at the Canada assembly plant as 2 wheel drive Extended Cab 1500 series trucks and were equipped with a torsion bar front suspension frame equipped standard with the LQ9 = 6.0L H.O.engine, M32 = 4L65E transmission, GT4 = 3.73 rear gear, and G80 Gov Lock as standard equipment. The 2004 models were equipped with the standard 10 bolt 8.625 rear end. The 2005 models were upgraded with the larger 14 bolt 9.5 rear end under RPO option AXN. The package also included one style of the newly introduced GM 20 inch wheels installed from the factory. This marked the first time the LQ9 engine was available for a two wheel drive application. Unlike the SS Package you could order the interior combination in anything from basic cloth to fully loaded. There were also more color options available with this package.
Hybrid
GM launched a hybrid version of the Silverado/Sierra in 2004, becoming the first ever GM hybrid passenger vehicle. Known within GM as the Parallel Hybrid Truck or PHT it is not actually a parallel hybrid by the current definition, but a type of micro hybrid design. The electric motor housed within the transmission flywheel housing, serves only to provide engine cranking/starting, battery charging, and powering accessories. The engine automatically shuts down as the truck comes to a stop and uses 42 Volt electric power to the starter/generator unit to restart the engine as the brake pedal is released. Besides the typical 12 V automotive battery the PHT uses three additional 12 V valve regulated lead acid (VRLA) batteries mounted under the rear seat to store and provide power. The truck uses a 5.3 L Vortec 5300 V8 for primary propulsion power. These trucks were also purchased back from customers for more than what they were worth in the late 2000s.
The PHT features four 120 volt 20 amp AC outlets, two in the bed and two inside the cab under the rear seat. These are particularly interesting to the building/construction contractor market, since they often require AC power when on the job. Additionally, the extra reserves of power for the accessories make this truck well-suited to that market, where trucks often sit at idle for hours at a time.
Availability was extremely limited at first, with commercial buyers getting the first allotment. Later in 2005, the truck was offered at retail in Alaska, California, Florida, Nevada, Oregon, Washington and Canada. For 2006-07 the truck was generally available to retail buyers throughout North America. The Parallel Hybrid Truck was discontinued for the 2008 model year with the release of the GMT900 truck line. Starting in 2009, General Motors offers a second generation Chevrolet Silverado and GMC Sierra equipped with a Two-Mode Hybrid powertrain and 4-speed CVT.

The HD variant is a heavy-duty light truck. It is a strengthened version of the Silverado/Sierra light-duty, and is available in the 1500HD, 2500HD, and 3500models. The 1500HD, introduced in 2001, offers a Vortec 6000 V8 with 300 hp (224 kW) at 5200 rpm and 360 lb·ft (488 N·m) of torque at 4000 rpm with a Hydra-Matic 4L80E four-speed automatic transmission. The 2500HD also offers an available Duramax V8 with 300 hp (224 kW) at 3100 rpm and 520 lb·ft (705 N·m) of torque at 1800 rpm. Also available is the Vortec 8100 V8 with 340 hp (254 kW) at 4200 rpm and 455 lb·ft (617 N·m) of torque at 3200 rpm.
The 2500HD has an available five-speed (six-speed for 2006-2007 models) Allison 1000 transmission. The Silverado 3500 offers the same engine/transmission features that the 2500HD does, however it is usually equipped with "dually" twin wheels at the rear and has a stronger suspension. The HD models are primarily used for towing and high-weight cargo.
Towing capacity for the 1500HD is rated at 10,300 pounds (4,700 kg), and can haul 3,129 pounds (1,419 kg) in the bed. The 2500HD ups these ratings to 16,300 pounds (7,400 kg) with the 8.1 liter engine or 10,600 pounds (4,800 kg) with the 6.0 liter engine, and 4,058 pounds (1,841 kg), while the 3500 can tow 16,700 pounds (7,600 kg) and haul 5,511 pounds (2,500 kg). The addition of 4 wheel drive tends to reduce the towing and carrying capacity by 200 to 400 lb (181 kg), depending upon year and model. Other factors, such as options, can also affect these numbers.

The all-new GMT900 generation of the Silverado/Sierra arrived in the last quarter of 2006 as a 2007 model. It features a redesigned exterior, interior, frame, and suspension as well as a power increases on certain engines. It takes styling cues from the 2007 GMT900 SUVs and the Chevrolet Colorado pickups. Like the GMT900 SUVs, these pickups also have greatly improved aerodynamics over their predecessors like steeply raked windshields and tighter panel gaps which improve fuel economy. The GMT800 models were continued in 2007 badged as "Classic", just as the GMT400 models continued for a year after the GMT800's introduction.
The new Silverado earned the North American Truck of the Year award for 2007 and was Motor Trend magazine'sTruck of the Year for 2007. Like its predecessors, the new Silverado offers buyers a choice of two door regular cabs, four door extended cabs (with rear doors that now open 170 degrees similar to the Nissan Titan) and four door crew cabs with the rear doors opening in the same direction as the front doors. GM also offers the trucks in the traditional two and four wheel drive configurations.
The Generation III small block V8 engines offered in the GMT 800 trucks will be replaced in the GMT 900 series by the Generation IV small block V8 engine family, featuring upgrades such as increased power and Active Fuel Managemen ton the 5.3 L and 6.0 L V8s. A new high performance 6.2 liter V8 (with 403 hp (301 kW) and 417 lb·ft (565 N·m) of torque) was introduced with the 2007 Cadillac Escalade and 2007 GMC Denali line, and is now available on the Silverado LTZ trim line. After skipping the 2008 model year, with 2007 being the last for the GMT800 hybrid line, a two-mode hybrid model will be introduced in late 2008 as a 2009 model.
There are two dash options offered in the new Silverado and Sierra. A luxury-inspired dash that closely mimics the dash in their GMT900 SUVs, and a "pickup" dash that is more upright to make way for a passenger seat in place of a center console.
As of 2008, General Motors full size trucks are no longer sold in United States and Canada with manual transmissions, they are only offered in Mexico in the Silverado 1500 V6 engine and Silverado 3500.
All Silverado & Sierra 1/2 ton models received a revised bumper and shortened front fascia mid-way through the 2009 model year and a full mid-cycle refresh followed with all 2010 models, including new interior door panels (which moved the handle forward and added an additional cup holder) and a six-speed automatic transmission on regular and extended cab models with 5.3L or larger V8's was also made standard. Two new exterior colors were added: Taupe Gray Metallic and Sheer Silver Metallic.
