Silverado HD powertrains

A Vortec 6.0L gas V-8 with variable valve timing is matched with the Hydra-Matic 6L90 six-speed automatic transmission as the standard powertrain across the Silverado HD model range. This combination delivers excellent performance and efficiency, with an emphasis on low-rpm performance. New for 2012, the engine is E85-capable.

The Duramax 6.6L diesel and Allison 1000 six-speed automatic transmission powertrain combination is available on all 2500HD and 3500HD models. Highlights of the Duramax diesel include:

  • 397 horsepower (296 kW) at 3,000 rpm.
  • 765 lb.-ft. of torque (1,037 Nm) at 1,600 rpm.
  • NOx emissions reduced at least 63 percent over 2010 models.
  • High-pressure (30,000 psi/2,000 bar) Piezo-actuated fuel system for greater fuel efficiency, improved performance and reduced emissions
  • Exhaust brake system that enables controlled vehicle slowdown on downhill grades without actuating the brakes
  • Selective catalytic reduction after-treatment system using diesel exhaust fluid (DEF) injection to provide the best overall diesel characteristics and performance – with a range of about 5,000 miles (8,000 km) between DEF refills
  • Combustion and after-treatment have been optimized to provide about 700 miles (1,125 km) between diesel particulate filter regenerations – a 75-percent improvement over the previous system and significant contributor to improved fuel efficiency, as the regeneration process requires additional fuel
  • B20 biodiesel capability for an alternative fueling option

The Allison 1000 features driver shift control with tap up/tap down shifting and a patented elevated idle mode cab warm-up feature. Also, the tow/haul mode reduces shift cycling for better control and improved cooling when towing or hauling heavy loads.

Silverado HD chassis and suspension

All Silverado HD models feature fully boxed frame assemblies – 18 different assemblies that accommodate all of the range’s configurations. Redesigned last year, the frames have increased cross sections and use more high-strength steel for greater durability, higher towing capacity and improved ride and handling compared to pre-2011 models. The front sections are hydroformed. Additional chassis and suspension features include:

  • Front axle weight rating up to 6,000 pounds (2,721 kg) front gross axle weight rating (FGAWR), enabling a snow plow to be used on all 4WD cab configurations with the available snow plow prep package.
  • Short-long arm/torsion bar front suspension features forged steel upper control arms and precision-machined cast iron lower control arms.
  • Five different torsion bar rates support five different front gross axle weight ratings to help stabilize the range of trim heights of various models under load, while enhancing appearance, handling, durability, tire wear and alignment. The trim height is adjusted on each bar via a single bolt, easily allowing the height to be changed to account for the weight of a snow plow or other accessories.
  • An upper shock mount attachment design that’s positively connected to the frame with two fasteners, eliminating squeaks and clunks, while supporting higher load capability and increased durability.
  • Asymmetrical leaf-spring design that minimizes axle hop and enhances traction control efficiency.
  • Two-stage leaf-spring design on 2500HD models and three-stage design on 3500HD model. All models feature 3-inch-wide (76 mm) leaf springs.
  • Z71 Off Road suspension is available on LT and LTZ models and includes includes 35mm deflective disk twin-tube shock absorbers, off-road jounce bumpers, 33mm front stabilizer bar and a skid plate package.
  • Four-wheel disc brakes with hydroboost are standard on all models.
  • Four-wheel, four-channel ABS is standard on all single-rear-wheel models and a three-channel system is standard on dual-rear-wheel models.
  • A Silverado 3500HD crew cab/long box can tow up to 23,000 pounds (10,432 kg) with a fifth-wheel hitch.
  • The maximum payload (3500HD) is 7,215 pounds (3,273 kg).
  • The frame-mounted hitch for conventional trailering has a box-tube design and supports up to 18,000 pounds (8,164 kg).

Silverado HD safety and crash-avoidance features

  • StabiliTrak electronic stability control system is standard on all single-rear-wheel models.
  • Large, four-wheel disc brakes with four-wheel ABS are standard on all models.
  • High-strength steel tubular frame cross member that enhances safety and improves crashworthiness.
  • Seat pelvic/thorax and head curtain side air bags available on 2500HD
  • Available rear vision camera system.
  • Trailer sway control system on all single-rear-wheel models.
  • Hill start assist is standard on single-rear-wheel models.

Trailer sway control system provides an added measure of confidence when towing a trailer. The system senses conditions of trailer sway and intervenes with braking and/or reduced engine power to bring the trailer under control and keep it on its intended path. The system will use electric trailer brakes when a trailer is plugged into the standard wiring harness of the truck and its performance requires no input from the driver.

The hill start assist system is automatically engaged when sensors detect the vehicle is on grade of about 5 percent or greater. It holds the brakes for about 1.5 seconds or until the gas pedal is pressed, preventing rollback – it is particularly effective when towing, giving the driver time to switch from the brake pedal to the gas pedal without rolling.

OnStar details

Silverado is offered with OnStar as standard on all models, except Work Truck, where it is optional. It uses GPS and cellular phone technology to automatically call for help in the event of crash. OnStar subscribers also can use the service to be Good Samaritans by sending help to other motorists, and to call for help in other non-crash emergencies.

The OnStar RemoteLink app allows Silverado owners to control OnStar functions from a smart phone.

  • OnStar is the leading provider of in-vehicle safety, security and information services in the United States and Canada.
  • Six months of complimentary OnStar Directions and Connections service with Turn-by-Turn Navigation for easier route guidance on all Silverado models. The feature is easy to use because all directions are sent to the car by an advisor, without the need to stop. Turn-by-Turn can be cost-effective, since map updates and aftermarket navigation systems are not needed.
  • Stolen Vehicle Assistance helps police track the vehicle.
