From Bumper to Bumper: Highlights of the 2021 Chevrolet Silverado 3500 HD Chassis Cab

Chevrolet is an icon of the American workforce because of its rich history and reputation for delivering powerful and capable workhorses that stand the test of time. These workhorses are usually found in Chevrolet’s truck lineup, especially in the commercial fleet, where business owners, contractors, electricians, and many others shop for powerful performers that offer complete customization. This is exactly what you’ll find in the 2021 Chevrolet Silverado 3500 HD Chassis Cab, which is one of the toughest and most capable rigs on the road.

What makes the Chassis Cab one of the top-sellers in Chevrolet’s commercial fleet? From its power under the hood and its towing capability to its customization options, the 3500 HD offers something for everyone. Here’s a closer look at the features you won’t want to miss as you shop for the all-new 2021 Silverado 3500 HD Chassis Cab.

Regular Cab or Crew Cab

Chevrolet gives you a choice between a regular or crew cab configuration on the 3500 HD Chassis Cab. For those needing to haul more equipment than passengers, the two-door regular cab is an ideal option since it offers seating for two and a configurable rear frame that can range anywhere between 60 to 84.5 inches in length. In contrast, the four-door crew cab offers seating for four with a 60-in rear frame. So, you can get a bigger cab to fit the whole crew, or utilize the extra space provided by the regular cab and opt for a longer frame.

Powertrain and Performance

Once you’ve selected between the regular or crew cab configuration, Chevrolet gives you a choice between two powertrain options. The 6.6-liter V8 gasoline engine is paired with a 6-speed automatic transmission that comes with Cruise Grade Braking and Powertrain Grade Braking. This combination delivers best-in-class standard torque of 464 lb-ft of torque and 401 horsepower. Of course, if you’re looking for more hauling capability, you can opt for the Duramax 6.6-liter turbo-diesel V8 engine and the 10-speed Allison automatic transmission. The turbocharged engine delivers exceptional performance and durability by producing 445 horsepower and 910 lb-ft of torque.

With the V8 gasoline engine, the 3500 HD is outfitted with four-wheel antilock disc brakes with Duralife brake rotors, external engine and transmission coolers, a high-capacity air cleaner, and a heavy-duty locking rear differential. Additional features include Hill Start Assist, Tow/Haul Mode, and Trailer Sway Control for added stability. The diesel engine comes with a 2-speed Autotrac transfer case, a wide-track rear axle, and an integrated brake controller.


Designed to tackle any job, the 3500 HD Chassis Cab offers plenty of power under the hood. But what does its capability truly look like depending on configuration and powertrain? There are minimal differences between the crew and regular cab configurations. The gross vehicle weight rating on both configurations is 14,000 lbs, and the maximum gross combination weight rating is between 24,000 and 40,000 lbs. The payload varies only slightly, with the regular cab offering 6,221 to 7,571 lbs and the crew cab offering 5,751 to 7,040 lbs.

So, what’s the best configuration? To reap the benefits of hauling, a regular cab 3500 HD with two-wheel drive delivers a maximum payload of 7,571 lbs. However, the most power comes from the Duramax diesel and its 910 lb-ft of torque. This achieves the 3500 HD’s full potential and delivers a maximum gross combination weight rating of 40,000 lbs.
