What's New

One year removed from its last overhaul, the 2021 Chevrolet Silverado 3500HD carries over, but with some changes of note. These include expanded towing capacity that now reaches 36,000 pounds at the top of the range. New special edition packages are available, and wireless Android Auto and Apple CarPlay phone projection capability rolls out.

Choosing Your Chevrolet Silverado 3500HD

Chevrolet offers the 2021 Silverado 3500HD in four trim levels: WT, LT, LTZ, and High Country. Pricing begins at $37,795 including destination for the base WT and reaches $65,295 for the range-topping High Country.

Engine Choices

The Chevy Silverado 3500HD comes with two engine choices. A 6.6-liter V8 gas engine is standard, while a 6.6-liter V8 turbodiesel engine is available across the model lineup for around $10,000 to $12,000. Models with the gas engine may be upgraded for flex-fuel capability.

The gas engine is paired with a heavy-duty six-speed automatic transmission. The turbodiesel works with an Allison 10-speed automatic. The Allison transmission may be upgraded to include integrated power take-off. Rear-wheel drive is standard, with four-wheel drive available. The High Country comes standard with 4WD.

The maximum payload amounts range from 7,145 to 7,442 pounds with the gas engine and 6,196 to 6,523 pounds with the diesel. When utilizing conventional towing, the gas model pulls up to 16,800 pounds, or 20,000 pounds with the diesel.

In models equipped with a fifth wheel/gooseneck connection, the gas-powered model pulls up to 17,200 pounds, while the turbodiesel version is rated as high as 36,000 pounds.

Passenger and Cargo Capacity

There are three cab styles available: regular cab, double cab, and crew cab. Regular cab model holds up to three people, while the double and crew cabs seat five or six.

There are also two bed sizes: the 98.27-inch long bed (available with all three cab styles), or the 82.25-inch standard bed (available only with crew cab).

Safety Features

There are no standard active safety features, which isn't too surprising in a heavy duty truck. However, some are available across a couple of packages.

The Safety Package ($890 to $1,090, depending on the trim) includes front and rear parking sensors, lane change alert, blind-spot monitoring, and rear cross-traffic alert. These features are finally standard on the High Country. The Safety Confidence Package ($615 to $645) bundles automatic emergency braking, forward collision warning, and more.


Chevrolet equips the Silverado 3500HD with a 7-inch touchscreen display, Bluetooth, one USB media port, and Apple CarPlay and Android Auto smartphone compatibility. Regular cab models come with a two-speaker audio system; the double and crew cab models have a six-speaker audio system.

Some models have an 8-inch color display and additional USB ports. Navigation, HD radio, a head-up display, and a wireless charging pad are also available.

WT - From $37,795

Chevrolet equips the base Work Truck with halogen headlights, recovery hooks, and all-season or all-terrain tires. Air conditioning, a split fold-down 40/20/40 front bench seat and a 60/40 split-folding rear bench seat in double and crew cab models are standard. Vinyl flooring and vinyl-covered seats are standard.

LT - From $41,895

Chrome bumpers, a trailer brake controller, and heated power-adjusted side mirrors are standard. LED headlights, daytime running lights, fog lights, and taillights are included. Other features include a remote start system, keyless entry with push button start, a heated leather-wrapped steering wheel, heated and power-controlled driver and outboard front passenger seating, cloth seats, and a 120-volt power outlet.

LTZ - From $53,995

Available on with the crew cab, the LTZ trim adds such features as LED fog lights, a power tailgate, and wheelhouse liners on single rear models. Upgrades to the transfer case and rear vision camera are included. A theft-deterrent system and dual-zone climate control are added.

High Country - From $65,295

Also only available with the crew cab, the High Country trim adds several standard features including four-wheel drive, assist steps, a spray-on bedliner, a power-up and down tailgate, and cargo area lighting.

CarsDirect Tip

Of the options in the 2021 Chevy Silverado 3500HD lineup, opt for the dual rear wheel arrangement for increased safety and stability while towing if needed. The turbodiesel engine is your only choice if your pulling needs exceed 20,000 pounds.
