The 2500 and 3500 come with a 6.0L V8 engine standard, though a 6.6L turbo-diesel V8 is available. All Silverados come with a heavy-duty 6-speed automatic transmission. The 2500 and 3500 can be had as either a regular, extended or crew cab, with a standard or long bed, and with either a two- or 4-wheel-drive configuration. Dual rear wheels are available on some models. There are three trim levels: WT, LT and LTZ.
The standard engine is a 6.0L V8 engine that is capable of 360 horsepower and 380 pound-feet of torque. It can also be ordered to run on compressed natural gas. A 6.6L turbo-diesel engine capable of 397 horsepower and 765 pound-feet of torque is also available. A fully-boxed chassis was introduced in 2011, which GM says is 125 times stronger than the unit it replaced and allows for a smoother ride as well as a much greater towing capacity. When equipped with the diesel engine, the trucks are now capable of towing up to 23,200 lbs.

In addition to the stiff frame, heavy-duty front and rear suspension systems yield incredible strength on four-wheel-drive models. Now rated at 6,000 pounds, all 4-wheel drive front suspension systems can easily support a snow plow when properly equipped. The 2500 utilizes 2-stage leaf springs in the rear, while the 3500 makes use of three-stage springs.

Some standard features cross all Silverado lines, such as driver and passenger air bags, four-wheel disc brakes with anti-lock brakes and tire pressure monitoring. GM's OnStar system is standard on the LT trim and better. It includes crash response, roadside assistance and remote door unlock services. There are two suspension packages available for the 2500: the Z85 handling and trailering suspension and the Z71 off-road package, which adds high-performance shocks and a bigger stabilizer bar.

Equipment availability is dependent on trim. Pretty much anything available in a pickup is available on a Silverado -- power everything, remote keyless entry, heated mirrors, privacy glass, bed liner, front tow hooks and chrome or aluminum wheels. Navigation is available, as is rear-seat entertainment for the crew cab models. Heated power seats are available, along with cruise control, sunroof and a rear window defogger.

High-tech touches such as a rearview camera and rear parking assist are optional, too, and would probably come in handy on a big truck like the Silverado. MP3-compatible stereo with XM satellite radio can be found on some models, and a Bose system with USB interface is available.

For 2015, the Chevrolet Silverado HD range receives a full exterior and interior redesign. Exterior styling changes match those found on the Silverado 1500 and result in improved aerodynamics and air flow. Interiors have also been restyled to improve comfort, quietness, and storage space. Stabilitrak with Trailer Sway Control is now standard on all models, and new 6.5- and 8-foot beds include standard "CornerStep" bumpers, EZ Lift and Lower tailgates and an LED bed light for nighttime work. In terms of performance, maximum payload has increased from 7,222 pounds to a best-in-class 7,374 pounds. Best-in-class conventional tow rating is now 19,600 pounds, up from 18,000, while maximum fifth-wheel tow rating is up from 22,500 to 23,200 pounds.

The Silverado range is always one of GM's biggest sellers. This means GM is always endeavoring to innovate and continue to improve the truck's design. As a result, the consumer wins -- whether hauling equipment to a job site, working a farm or towing a boat, the Silverado 2500 and 3500 are built for tough work, and they are some of the best-designed trucks available from any manufacturer. Made in either short- or long-bed form, with two- or 4-wheel drive, optional dual rear wheels and with a choice of several impressively powerful engines, the Silverado can be set up do just about anything asked of it. The 2500, even simply configured, is capable of towing a massive load and base prices start around $31,000.
