Chevrolet Silverado HD

SILVERADO HD POWERTRAINS
A Vortec 6.0L petrol V8 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. It is rated at 360 horsepower (268 kW) and 380 lb.-ft. of torque (515 Nm).
The bi-fuel version of the 6.0L engine – known by its LC8 engine code – features special hardened valves and valve seats that enables it to run on compressed natural gas (CNG) or gasoline. 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:

296kw (397hp) at 3,000 rpm
1,037nm (765lb-ft) of torque at 1,600 rpm
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 optimised to provide about 1,125km (700 miles) 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. The front sections are hydroformed.
Additional chassis and suspension features include:

Front gross axle weight rating up to 2,721kg (6,000lb), 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
Four different torsion bar rates support four different front gross axle weight ratings to help stabilise 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 minimises 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 35mm deflective disk twin-tube shock absorbers, off-road jounce bumpers, 33mm front stabiliser bar and a skid plate package

Silverado 2500HD and 3500HD remain the benchmarks for heavy-duty pickups, strengthening Chevrolet’s 95-year reputation for building dependable, hard-working trucks.
