2004 GMC Sierra

ROOMIER CABS, MORE DRIVER-FRIENDLY FEATURES, POWER INCREASES UNDERSCORE SIERRA AND SIERRA HD'S PROFESSIONAL-GRADE LEADERSHIP

GMC's 2004 Sierra and Sierra HD full-size pickups prove once again why they are their respective segments' premier series of trucks. New for 2004 are a roomy and comfortable half-ton 1500 Series Crew Cab in two- or four-wheel drive, a three-quarter-ton 2500 Series Crew Cab rated at 8,600 pounds GVWR and available in either two- or four-wheel drive, and a one-ton 3500 Series single-rear-wheel model rated at 9,900 pounds (4,491 kg) GVWR available as a 4WD long-box in Regular, Extended or Crew Cab configurations.
'From the 1500 crew cabs to single-rear-wheel trucks with one-ton work capabilities, Sierra is poised to completely redefine the premium truck market in 2004,' said Sierra Marketing Director Sam Mancuso. 'With the addition of a true half-ton Crew Cab and the maneuverable, single-rear-wheel one-ton, GMC now offers a complete line of Professional Grade products to fill the needs of practically every truck buyer.'





Powered by a standard Vortec 5300 V-8 with 285 horsepower (201 kw) and 295 lb.-ft. (386 Nm) of torque, the new 1500 Crew Cabs have GVWRs of 6,800 and 7,000 pounds (3,084 and 3,175 kg). With payloads ranging up to 1,934 pounds (877 kg) and maximum trailering capability of 8,500 pounds (3,856 kg), they are more than competitive in handling any light-duty assignment.

Meanwhile, in the three-quarter-ton segment, Sierra's C/K 2500 Series short-box models get additional room to comfortably seat up to five full-size adults. The 2500 Series Crew Cab models are now available in either 2WD or 4WD, and are rated at a hefty 8,600 pounds (3,901 kg) GVWR.



Three very Professional Grade 3500's
Also new in 2004 is the 3500 series single-rear-wheel one-ton Sierra, available in Regular, Extended and Crew Cab configurations as a 4WD long box, and rated at a no-nonsense 9,900 pounds (4,491 kg) GVWR. These new heavy-duty models, slated for introduction in the first quarter of 2004, are also available in a chassis cab, 'box-delete' configuration.

The 3500 Series features a standard Vortec 6000 V-8 and Hydra-Matic 4L80-E four-speed automatic transmission or, for increased power, customers can opt for the award-winning Duramax 6600 turbo-diesel or the Vortec 8100 gasoline engine. The new 3500 Series models offer impressive trailering capability of up to 15,700 pounds (7,121 kg) with a fifth-wheel or gooseneck trailer and payload-carrying capability of up to 4,239 pounds (1,923 kg).

The new available single-rear-wheel (SRW) axle makes the 4WD 3500 Series models ideal for customers who need one-ton capabilities in an easier-to-maneuver configuration. Sierra C/K3500 dual-rear-wheel models, rated at 11,400 pounds (5,171 kg) GVWR, will continue to be available in Regular Cab, Extended Cab and Crew Cab configurations for those who need the extra payload capacity.

The new K3500 Series Chassis Cab (box-delete) models offer the easier-to-maneuver single-rear-wheel configuration to customers who require one-ton capabilities with special service bodies. These trucks also have a standard G80 locking rear differential for increased traction, when required. A 4.10 axle ratio is standard with the Vortec 6000 and Vortec 8100 and a 3.73 axle ratio, standard with the Duramax 6600. The new one-ton SRW trucks use a specially designed three-stage multi-leaf rear suspension and custom shock absorption system to provide the optimal combination of ride, performance and handling.

Work Truck Package available across the board
For the first time, the Work Truck Package is available on all Sierra and Sierra HD models. It features a unique front-end appearance that sets it distinctly apart from other trim levels. Meanwhile, all base models have an attractive chrome grille-surround, chrome steel wheels, a chrome rear bumper and cruise control as standard equipment. More chrome throughout the model lineup enhances the truck's premium look.

New 17-inch aluminum wheels with low-rolling-resistance tires are now available on four-wheel drive 1500 Series pickups. And, the optional Z82 trailering package available on both Sierra and Sierra HD for 2004 offers everything customers need for safely towing larger trailers in a single package, featuring items such as a heavy-duty hitch platform, an integrated electric brake connection, wiring harness, and a high-capacity air cleaner.

Improved safety
1500 Series pickups feature improved safety with a right front passenger safety-belt reminder, which lets the passenger automatically know via a chime and indicator light if their safety belt hasn't been fastened. This system complements the automatic passenger-sensing air-bag system (first introduced in 2003) that automatically deactivates the passenger-side air bag under certain conditions to help protect smaller occupants. The system assesses whether the occupant in the seat is an adult or child, based on the measured weight in the seat cushion and tension in the belt system. If these measurements are typical for a small occupant or child in a booster seat, for example, the air bag is automatically disabled. An indicator light in the rearview mirror lets the driver know if this system is on or off.

Great sound and entertainment systems
Sierra's family of radios ranges from the base radio/CD unit with a four-speaker system to an integrated AM/FM radio with a six-CD changer, RDS readout and a Bose Sound System with six speakers and a subwoofer.

The OnStar safety and security system is available on SLE trim levels and standard on SLT trim levels and on the Denali. For nationwide listening capability, customers can upgrade to the available XM Satellite Radio (continental Ú.S. only) package. In addition, the Denali and all SLT trim models feature a standard six-disc in-dash CD changer coupled to a premium Bose six-speaker sound system with sub-woofer, AM/FM radio, cassette and remote. Available RDS (Radio Data System) audio receivers allow vehicles to receive information such as station call letters, music genre, emergency broadcasts, song titles and other information.

Crew Cab models offer an optional rear seat DVD entertainment system. The DVD system includes a 7-inch (178-mm) screen, flip-down, color liquid-crystal display and the capability of playing studio-quality audio/video in both CD-audio and DVD formats and includes two sets of wireless (infrared) headphones with independent volume control, a wireless remote control and three sets of auxiliary video and audio inputs.
