2009 GMC SIERRA HEAVY-DUTY TRUCKS ARE BUILT TO WORK

Designed for hauling everything from a construction crew and their equipment to race car trailers and other large leisure “toys,” Sierra heavy-duty trucks are offered in a range of extremely capable 2500HD (three-quarter-ton) and 3500HD (one-ton) models.

The 2009 Sierra HD lineup advances GMC’s century of experience building nothing but trucks, exemplifying the brand’s engineering excellence and delivering vehicles that customers can rely on for any task.

Sierra heavy-duty trucks are available in Work Truck, SLE and SLT trims. The range of configurations – three cab styles, three cargo box styles and five wheelbase lengths – delivers tremendous choice. Some full-size truck manufacturers do not even offer three-quarter-ton or one-ton heavy-duty trucks. And among those that do, the Sierra HD pickups offer many segment-best capabilities, including 18,500-pound (8,392 kg) gross combined vehicle weight rating for vehicles with a gas V-8 and a 13,000-pound (5,897 kg) conventional trailer weight rating enabled by a larger-capacity trailer hitch platform. Maximum towing capacity is 16,500 pounds (7,484 kg), when equipped with a fifth-wheel hitch.

For 2009, changes to the Sierra 2500HD and 3500HD lineup include a number of safety-related and convenience features that bolster an already comfortable and refined driving experience. They include:

Sierra HD design

Sierra HD models have a distinctive front end with a prominent GMC emblem set in a large, chrome-ringed grille. SLT models feature large foglamps set into the bumper, creating an upscale appearance that further reflects GMC’s brand identity.

The trucks are refined looking, too, with doors that extend over the rockers for a smooth, uninterrupted look, and large headlamps. The door handles feature large, grab-style designs that are easy to open with gloves. Tolerances between panels are minimal – including a 50-percent reduction in the space between the cab and cargo box – which enhances the overall sleekness of the design.

Cab and cargo box configurations

Sierra 2500HD and 3500HD are offered in regular, extended and crew cab configurations, which are complemented with standard (6-foot 6-inch) and long (8-foot) cargo box lengths. Sierra 3500HD models also are available with the Dually dual rear wheel configuration on a long (8-foot) box. Features on extended models such as 170-degree-opening (164 degrees with dual rear wheels) rear access doors with fully retractable power windows offer increased versatility.

The pickup boxes have great versatility, strength and capacity. A one-piece wheelhouse and inner box side offers strength and a smoother, more integrated appearance. The boxes are 1.18 inches (30 mm) deeper in the front and 1.57 inches (40 mm) deeper at the rear than previous-generation models, with stronger inner walls that offer improved performance when fitted with ladder racks, toolboxes and other accessories. Cargo bed volume is 60.7 cubic feet (1,718 L) with the standard box and 75.5 cubic feet (2,138 L) with the long box.

Dually cargo boxes are completely made of steel, including hydroformed sheet metal outer fenders. They have a smooth, integrated appearance and enhanced strength. All Dually models feature marker lights on the fenders and sleek cab roof lights that are aerodynamically integrated into the top of the cab.

The tailgate designs include a lock and an available EZ Lift feature, with torque-rod assist. The tailgates are also easily removed by simply opening to 45 degrees and pulling straight out and away from the vehicle.

Cargo management system

An innovative cargo management system is available and is complemented by a range of dealer-ordered accessory packages. Three rails that run the length of the box sides and the forward box wall are secured with high-strength anchors and, unlike competitors’ systems, incorporate upper and lower tracks. Four adjustable tie-down brackets are included with each system and can be located anywhere on the tracks, each rated for a load point of 500 pounds (227 kg).

At the heart of a comprehensive accessories portfolio for the pickups is a group of specific accessory products designed to integrate into the cargo management system. The rails enable the use of an overhead utility rack rated at 500 pounds (227 kg) loading capacity, a sliding diamond plate toolbox, a sliding bed divider and diamond plate side storage boxes. These accessories use either the upper or lower rails, allowing numerous combinations that can easily fit together or bypass one another as they slide along the rails. The toolboxes use a codeable lock, enabling the vehicle key to be used for locking and unlocking these accessories.

Interior refinement

GMC Sierra 2500HD and 3500HD are quiet, spacious and refined inside. Each features two distinct interior designs that reflect their respective brand identities, including specific trim, appointments and gauge cluster appearance.

Base- and midlevel-trim models include a functional pure pickup interior design theme with a contemporary adaptation of GM’s ergonomic cockpit instrument panel design. In addition, this interior includes specific door panels with large door pull and release handles, as well as unique seat configurations; center console and underseat storage systems. It also includes two glove boxes (a traditional lower glove box and a covered upper storage compartment).

Luxury-inspired premium interiors are standard on SLT models. They offer richly appointed features, including a distinct instrument panel design, large-capacity center console (20.1 L), specific door panels, seats and other trim elements. An SLT Convenience Package includes adjustable power pedals, universal home remote, locking EZ-Lift tailgate and rear parking assist.

Spaciousness in each interior trim level is enhanced with “low and forward” instrument panels that provide a more airy feel to the cabin as well as a panoramic field of vision. The instrument panels are mounted approximately 3.5 inches (90 mm) down and forward on the pure pickup interiors, while the premium interior instrument panel is located 5 inches (127 mm) down and forward. Both instrument panel designs are integrated into their specific door panels to create a swept appearance.

All interiors are refined and craftsmanship is highlighted by flush surfaces, tight gaps and tolerances on the instrument panel, center stack, clusters and other components. Most gaps on the instrument panels and clusters are 0.5 mm or less. Attention to detail was given to conceal fasteners and metal structural components of all seats. There is no exposed hardware in the interior or doorsills. Soft-touch and low-gloss finishes for the instrument panels and other trim pieces are used throughout. The color and grain of the materials were carefully selected to provide a premium look.

Complementing the interiors’ finely crafted look and feel is exceptional quietness. All trim levels – even base work truck models – benefit from a comprehensive system that delivers a passenger environment almost devoid of noise. This is achieved with the use of strategically placed sound-deadening and sound-absorbing material in the body structure – including liquid-applied dampener on the floor and front-of-dash – as well as the inherent, vibration-minimizing traits of the stiffer frame and quieter attributes of the aerodynamically tuned exterior. Also, improved-design door sealing and a doors-over-rockers design help eliminate road and wind noise.

Interior features and amenities

Sierra heavy-duty interiors include the following features and amenities:

Powertrains

The standard engine is a 6.0L gas V-8 with variable valve timing. It is rated at a best-in-class 360 horsepower (268 kW) and 380 lb.-ft. of torque (515 Nm)* on single rear-wheel configurations (up to 10,000 pounds gross vehicle weight rating). Variable valve timing helps improve performance and fuel economy.

For models with a gross vehicle weight rating greater than 10,000 pounds, the 6.0L engine is rated at 322 horsepower (240 kW) and 380 lb.-ft. (499 Nm).

A Hydra-Matic 6L90 six-speed automatic transmission is paired with the engine. This powertrain combination offers a higher maximum gross combined weight rating (GCWR) – 18,500 pounds (8,392 kg) – than previous gas-powered combinations and is the segment leader for vehicles with a V-8 gas engine. The 6L90 has a wide, 6.04:1 overall ratio – including two overdrive gears – that helps deliver an excellent balance of performance and fuel economy. It also offers manual range selection and tap up/tap down control.

A clean and powerful Duramax 6.6L turbo-diesel engine is available. It continues to lead the segment in power and torque, with power ratings of 365 horsepower (272 kW) and 660 lb.-ft. of torque (895 Nm). A diesel particulate filter system helps provide a 90-percent reduction in particulate matter and a 50-percent reduction in NOx, compared with pre-2007 standards.

The renowned Allison 1000 six-speed automatic transmission is partnered with the Duramax 6.6L turbo-diesel engine. It delivers good fuel economy, quietness and control. It features a class-first range selection function, which allows the driver to easily select the desired gears to match driving conditions, such as towing a trailer on a steep grade.

Chassis and driving experience

Working in concert with the powertrains are a strong chassis and responsive suspension systems. The vehicle frame is comprised of a sturdy ladder design that is reinforced with cross braces. It features a segmented design that enables easy and accurate adaptation of numerous lengths to accommodate the trucks’ five wheelbase lengths. The frame sections are joined with strong, overlapping segments that bolster overall strength and rigidity.

The strength of the frame and enhanced capabilities enabled by the powertrain systems allow the Sierra heavy-duty trucks to offer a larger, 2.5-inch trailer hitch receiver platform. This enables the trucks to pull a segment-leading maximum of 13,000 pounds (5,897 kg) with conventional trailers. Trucks with fifth-wheel hitches can tow up to 16,500 pounds (7,484 kg), when properly equipped.

Additional features:

All heavy-duty models are available with an integrated trailer brake controller. It is integrated with the ABS system and provides immediate and measured brake force signaling to the electric-controlled trailer brake system. There is no requirement for external and/or aftermarket brake control systems. The brake controller switch is conveniently mounted on the lower-left section of the instrument panel.

Safety details

Sierra heavy-duty models are designed to help drivers avoid crashes and protect passengers in the event one occurs. The robust ladder frame and strong body structure provide occupant protection. The frame is designed with crush zones that crumple to absorb crash energy, while the body structure incorporates the strategic use of high-strength steel and structural adhesives designed to help maintain passenger compartment integrity and manage energy in a crash.

Additional safety features include:

All retail models come standard with the OnStar system, including a one-year subscription to the Safe & Sound plan. The OnStar service includes the Advanced Crash Response System, making crash data available to emergency services to potentially dispatch the appropriate life-saving personnel and equipment to crash scenes faster. If the vehicle is in a crash that activates an air bag, the OnStar system automatically notifies an OnStar advisor, who will check on the occupants or summon emergency help if necessary. OnStar also can assist authorities in locating a vehicle if it is reported stolen and provides remote door-unlocking service (when the vehicle is equipped with power locks).
