Today’s work truck drivers have something to be excited about: the 2021 Chevy Silverado 3500 HD Chassis Cab. Is it a work truck? Yes. But at its core, it’s a Chevy Silverado, made with high-strength steel, equipped with an available turbo-diesel engine, and equipped with comfort and convenience features that drivers on the roads can really use. Sensible storage compartments, technology that keeps you connected, and features that operate in the same way as the Silverado you drive home at night make this model the perfect work companion. No surprises. Just honest, Chevy power in a heavy-duty chassis cab format.
Gone are the days where large work-focused trucks would lumber slowly down the roads while drivers braced themselves against uncomfortable seats, gripping sticky steering wheels, feeling every bump in the road from those oversized tires. Chevy has taken the power of those old work beasts and combined it with the everyday luxuries modern truck owners expect. Put all the good parts together, and you get the 2021 Chevy Silverado 3500 HD Chassis Cab.
The 2021 Chevy Silverado 3500 HD Chassis Cab comes with a choice of a gasoline-powered or a turbo-diesel 6.6L V8 engine. The gas version of this engine boasts the best-in-class standard torque rating, at 464 lb-ft, which is matched with 401 horsepower. This engine is engineered with direct injection, variable valve timing and includes a deep-skirt cast iron engine block. In a nutshell, it’s a powerful beast that isn’t going to back down from a tough job.
The gasoline-powered engine is paired with a highly capable six-speed automatic transmission, featuring Cruise Grade Braking and Powertrain Grade Braking. Hill Start Assist and Tow/Haul mode are also standard with this engine, along with Trailer Sway Control, keeping this massive vehicle safe even when it’s pulling heavy duty. To keep this mighty engine healthy, Chevy has added a standard external engine oil cooler and external transmission oil cooler, so you can do your job as intended, without the risk of overheating.
If you need even more, the Duramax turbo-diesel version has you covered. With 445 horsepower and 910 lb-ft of torque, this engine is capable of towing and hauling the highest possible loads for the Silverado 3500 HD Chassis Cab. This engine is like no other in the segment, boasting an exclusive air induction system with a variable geometry turbocharger. The name of the game is performance, and the Turbo-Diesel never forgets a name. The available Duramax Turbo-Diesel engine is paired to an Allison 10-speed automatic transmission, and drivers have the opportunity to add an optional two-speed Autotrac transfer case and an integrated trailer brake controller, as well.
All 2021 Chevy Silverado 3500 HD Chassis Cab models are designed with power and performance in mind. The frame has been upgraded with high strength steel where it counts. The U-joints have been upgraded from the previous generation, and the axles are larger than ever before. The turbo-diesel models include 12-inch ring gear and a standard exhaust brake, but all models include a heavy-duty locking rear differential. Chevrolet has also engineered the Silverado 3500 HD Chassis Cab to be versatile, so you can upfit it in many different ways. From service/utility vehicle, dump bed, flatbed/stake, and more, this truck can accommodate multiple body types and styles for any job.
Jobs come in all sorts of different shapes and sizes, so it stands to reason a work truck should be just as flexible as the workers who drive them. The 2021 Chevy Silverado 3500 HD Chassis Cab is offered in Regular Cab and Crew Cab configurations, as well as a choice of 60-inch or 84.5-inch cab-to-axle lengths.
The regular cab models seat three and feature a standard 40/20/40 split-bench seat with a covered armrest, which offers storage space for items you might want to keep in check during transit. The total cab measures 126.5 inches, which translates into 44.5 inches of legroom to stretch out between jobs. Behind the regular cab is 60 or 84.5 inches of cab-to-axle space, ready to be upfitted for your job. The Gross Vehicle Weight Rating (GVWR) for regular cab models is 14,000 pounds, with a maximum payload ranging between 6,221 and 7,571 pounds. The Gross Combined Weight Rating (GCWR) of regular cab models ranges between 24,000 and 40,000 pounds, depending on outfitting and the engine selected.
The crew cab models are offered with a 60-inch cab-to-axle length only to accommodate the larger cabin. Measuring 157.0 inches, the crew cab includes standard 40/20/40 bench seats for three passengers in front, but drivers have the option to select two bucket seats instead. In the rear, crew cab models include a 60/40 folding bench seat for three passengers, including a child seat top tether. The Silverado 3500 HD Chassis Cab crew cab models have a slightly lower maximum payload between 5,750 and 7,040 pounds, but the GVWR and GCWR remain the same.
Since the 2021 Chevy Silverado 3500 HD Chassis Cab is designed for fleet and commercial purposes, many of the features are available at the driver’s discretion. Two trims are offered: the WT (Work Truck) and the LT. All Silverado 3500 HD Chassis Cab models include StabiliTrak Electronic Stability Control Syst. There is a host of standard airbags, including seat mounted side-impact and dual-stage frontal airbags for the driver and front passengers, head-curtain airbags for front and rear outer passengers, and a Passenger Sensing System for the operation of the front passenger-side airbag.
Inside, drivers will be pleased to find a six-speaker audio system, along with the same Chevrolet Infotainment 3 system they might find in any 2021 Silverado. This is displayed on a 7 or 8-inch diagonal color touchscreen, depending on trim, with an AM/FM stereo, Bluetooth audio streaming for up to two compatible devices, voice command capability, two USB ports, and connectivity through Apple CarPlay and Android Auto. The cargo area lamp is illuminated with a cab-mounted switch, which makes outside tasks in the dark much safer. Daytime running lights are also standard, along with roof marker lamps, recovery hooks, and power door locks in crew cab models.
Additional features can be added, either separately or through one of the many Fleet and Convenience packages offered by Chevrolet. These include a 4G LTE Wi-Fi hotspot and OnStar connectivity for those who need to stay in touch while they’re on the road. Additionally, drivers can add a 120V power outlet, carpet in place of the easy-care vinyl that comes standard, dual-zone automatic climate control, under-seat lockable storage compartments, and heated front seats to improve the overall comfort and convenience of the cabin.
