The standard engine is a 6.0L V8 engine that is capable of 360 horsepower and 380 lb-ft of torque. It can also be ordered to run on compressed natural gas. A 6.6L turbo-diesel engine capable of 445 horsepower and 910 lb-ft of torque is also available. When equipped correctly, a 3500HD is capable of towing up to 23,000 pounds.
In addition to the stiff frame, heavy-duty front and rear suspension systems provide incredible strength on 4-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 two-stage leaf springs in the rear, while the 3500 makes use of 3-stage springs.
Some standard features cross all Silverado lines, such as driver and passenger air bags, 4-wheel disc anti-lock brakes and tire pressure monitoring. GM's OnStar system is standard on the LT trim and better. Like most GM vehicles on which it's equipped, OnStar offers crash response, roadside assistance and remote door unlock services. There are two suspension packages available for the 2500: the standard 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 available as well. An MP3-compatible stereo with XM satellite radio is standard on many models. A high-performance Bose system with USB interface is available.
