The 3500HD offers a standard 6.6-liter V8 gas engine with 401 horsepower and 464 lb-ft of torque. A 6.6-liter Duramax Turbo-Diesel V8 engine is also available, which offers 445 horsepower and 910 lb-ft of torque. While the horsepower figures of the two engines are similar, the massive difference in torque gives them dramatically different capabilities. A heavy truck needs more torque to start moving and keep moving, which is why, many times, a diesel engine is a right choice for serious work. A 6-speed automatic transmission with Cruise Grade Braking and Powertrain Grade Braking is standard in the 3500HD. However, the diesel engine comes with an Allison 10-speed automatic transmission, and a 2-speed Autotrac transfer case is also an option.
Other standard performance features include an external engine oil cooler, a high-capacity air cleaner, an external transmission oil cooler, hill start assist, and trailer sway control. Trailer sway control works to enhance driver confidence while towing a trailer or other objects. It can sense when a trailer begins to sway and will intervene by reducing engine power and applying braking to bring the trailer back under control. Hill start assist makes it easier for a driver to pull away from a stopped position when the truck is on either an uphill or downhill slope, thus preventing a scenario in which the truck unintentionally rolls backward or forward. Other optional performance features include a wide-track rear axle and an integrated trailer brake control, which provides easy adjustment of trailer brake gain.
Productivity & Capability
The 2021 Silverado 3500HD Chassis Cab comes with numerous productivity features, both standard and available. Some standard productivity features include a 40/20/40 three-passenger split-bench front seat with covered armrest storage, a cargo area lamp with a cab-mounted switch, a driver information center, and vinyl floor coverings. The Chevy Infotainment system is standard and includes a 7-inch diagonal color touchscreen with Bluetooth technology, and supports Apple CarPlay and Android Auto so your drivers can stay connected while on the road. There are also two USB ports for charging electronic devices.
There are numerous optional productivity features available for the Chevy Silverado 3500HD Chassis Cab. You can choose an engine block heater, heated front seats, keyless open and start, a Snow Plow Prep Package, and even an integrated power take off. The power take off is particularly important as it makes it easy to install upfits that demand mechanical power from the engine. However, we find that the snowplow prep package is in particularly high demand given the Albany climate. This package is not only designed to simplify the process of mounting a snowplow on the truck, but it also features an uprated front axle, a high-output alternator, and provisions for mounting emergency lights on the roof for improved safety.
The Chevy Silverado 3500HD Chassis Cab is all about payload and towing. It is the type of truck you want when you need to get big jobs done. In addition to its rugged construction and robust suspension, the 3500HD is second to none in the torque needed for heavy hauling applications. If you are torn between the Silverado 2500HD and the Silverado 3500HD, just take a good look at your towing and hauling needs to make a better determination.
With a starting MSRP of $35,000, you are getting a lot of truck for your money - a lot of truck with exceptional power. To better help you tackle those big jobs, the 3500HD offers a max payload of 7,571 lbs. You need a strong foundation as well as a powerful engine for such a payload, and obviously, this truck delivers.
The gross combined weight rating (GCWR) for the Chevy 3500HD is 40,000 lbs. Gross combined weight rating is the maximum allowed weight of the truck, passengers, cargo, and trailer. This is particularly important to pay attention to in a work truck, as it is not uncommon to have a full load in the bed while towing a heavy trailer. The gross vehicle weight rating (GVWR) on the Chevy Silverado 3500HD is 14,000 lbs. That is the maximum total safety weight of your truck, including curb weight, plus the weight of passengers, upfits, and cargo.
If you need to tow something, the Chevy Silverado 3500HD can tow up to 36,000 lbs. To put that number into perspective, 36,000 lbs it's about what 36 full-grown Kodiak bears weigh, not that you would need to tow Kodiak bears, but it is nice to know you could, should the need arise. It's enough sheer power to tow two average-sized sailboats or a dozen race cars. You won't need to utilize all of that towing power all of the time, but it is good to know that you are prepared should you need to tow some heavy loads. The Silverado 3500HD's 36,000 lbs of towing capacity is one of the highest in its class and a very good reason why Chevy work trucks are so highly-touted.
The 2021 Silverado 3500HD Chassis Cab features a StabiliTrak Electronic Stability Control system as is a standard safety feature. This system employs sensors to tell when a wheel on the truck is slipping, and the system then applies the anti-lock brakes on the slipping side. This diverts more power to the wheels that are not slipping, approximating the effect of a locking differential. Chevy's StabiliTrak system is unique in that not only does it stop wheel slippage, but it can also alter the trajectory of the truck. The system can identify when the driver is losing control of the truck and applies brake pressure while decreasing engine power to help avoid an accident.
There are also several optional safety features for this work truck, including fog lamps, a backup alarm, OnStar-embedded hardware, and heated, power-adjustable trailering mirrors. Sometimes it helps to have specialized equipment when towing a large trailer. The optional towing mirror is vertically-orientated, which provides a greater depth of range. The top portion of the mirrors are heated, and the lower convex mirrors allow the driver to see their blind spots better.
