For heavy-duty work, you need a heavy-duty pickup like the 2021 Silverado 3500 HD, a top-of-the-line truck with unstoppable towing power, and a rugged design built for demanding tasks. Chevrolet's premier heavy-duty pickup is back with a new model year designed to not only elevate the pickup when it comes to workload and trailering but also include some additional much-requested amenities that improve the overall value of the truck.
Much like previous model year iterations, the 2021 Chevy Silverado 3500 is available in multiple trim formats and configurations. There is the base WT trim, the LT, the LTZ, and the High Country luxury trim. You will also find that the Silverado 3500 HD is available with four different drivetrain configurations, including a rear-wheel drive, four-wheel drive, dual-rear-wheel drive, and dual four-wheel drive setup. This opens up the 2021 Chevy Silverado 3500 to a multitude of uses, especially with the ability to configure the bed length and cab size.
There are two powertrain options available for this heavy-duty pickup. The base 2021 Chevy Silverado 3500 HD has a powerful 6.6-liter V8 engine paired up with an 8-speed automatic transmission, ensuring that the revolutions generated to produce 464 lb-ft of torque and 401 horsepower are delivered to the drivetrain without missing a beat, whether you have a rear-wheel or four-wheel drive setup. The 6.6-liter V8 has been a stable and reliable option for the heavy-duty Silverado 3500 HD after debuting for the 2020 model year, and it returns as a fan-favorite option for the combustion-based engine.
However, if you need that extra edge out of the Silverado's capabilities and performance ceiling, an alternative powertrain option is available in the format of the tried and trusted 6.6-liter V8 turbo-diesel from Duramax. This engine generates a massive 445 horsepower and an exceptional 910 lb-ft of torque that is fed into the drivetrain through the highly lauded 10-speed Allison transmission. A proprietary air-induction system and variable geometry turbocharger help the Duramax achieve these impressive numbers for the pickup.
The variable geometry turbocharger helps regulate boost for the engine and ensure optimal performance without a loss in power, nor is there an over-extension of fuel consumption. With the engine block heater and exhaust brake, the 6.6-liter Duramax V8 is the optimal choice for those who need efficiency, power, and unbridled torque in equal measure. The aforementioned 10-speed Allison automatic transmission comes equipped with six-disc clutches and four hall effect sensors that inform the transmission control module how to effectively shift based on the power output from the engine. What this does is ensure that the right gears are transferring the right amount of torque to the driveline, making certain that the Silverado 3500 HD is performing at peak performance based on its speed at all times.
The electronically controlled clutch system with overdrive ensures that there is always a smooth transition between gear shifts, especially when using the Tow/Haul Mode that comes standard with all 2021 Chevy Silverado 3500 pickup trucks. In turn, the electronically controlled clutch system in Tow/Haul Mode helps reduce the need to scavenge for gears when under heavy load. With improved cooling and power transfer efficiency, this makes the combination of the Duramax 6.6-liter V8 and Allison 10-speed automatic transmission perfect for heavy hauls, large cargo, and intense trailering.
The engineers at General Motors set out to break the mold with the 2021 Chevy Silverado HD series, and they did just that with the all-new max trailering rating, which tops out at an extremely impressive 36,000 pounds, making it a class defining entry in the heavy-duty pickup market. The 36,000-pound max tow rating is an increase over the 2020 Chevy Silverado 3500 HD's 35,500 tow rating, and this was achieved thanks to upgrades made to the truck's suspension and wheel packaging, which enabled the engineers to squeeze an even higher rating out of the Chevy Silverado. The new trailer rating is also possible when the pickup is configured as a Work Truck trim in a dual rear-wheel drive format with a Regular Cab and the Duramax 6.6-liter Turbo-Diesel V8 and Allison 10-speed automatic transmission.
When properly equipped with the Gooseneck/5th Wheel Package, which comes with a bed-mounted 7-pin trailer harness, a hitch platform for the gooseneck, an integrated brake controller, and stamped bed holes with caps installed, you will be ready to take on even the most challenging of trailer loads without a problem. New trailer ratings are only as useful as the trailering is functional. In other words, what good is being able to trailer large loads if you don’t have the technology to make full use of the trailer rating? For the 2021 Chevy Silverado 3500 HD, the technology is certainly there.
As part of the increase of being able to tow up to 36,000 pounds worth of cargo, all new trailering technology has been made standard for the Silverado 3500 HD, including up to 15 unique camera views so you can see exactly where the truck is positioned relative to the trailer at all times. A suite of technological features such as trailer length indicators and jack-knife alerts are instrumental in trailering safely to your destination. In addition to this, the view enhancements for the rear side and cargo bed view ensure that the trailer is never outside of your sight, while the guidelines and trailer-angle indicators give drivers a heads-up on if there's sway or if the truck and trailer are misaligned.
The new trailering technology makes it easy and convenient to load up large loads with confidence, knowing that you're in safe hands with the 2021 Chevy Silverado 3500 HD. For payloads, the 3500 HD can carry up to 7,442 pounds worth of cargo with a dual-rear-wheel driveline and outfitted in a Regular Cab format with the 6.6L V8 engine. So, you've got plenty of capability for whatever you need your truck to be able to do most.
Across the three cab formats, including Regular Cab, Double Cab, and Crew Cab, you have ample space for multiple passengers. The Regular Cab seats three and features a maximum bed cargo volume of 83.5 cubic feet with the long bed. What the Regular Cab lacks in passenger space it makes up for with its higher towing and cargo payload ratings. The Double Cab also offers up to 83.5 cubic feet of cargo volume with the long bed option and can seat up to six people. The balance with the Double Cab is that it doesn't reach the class-defining towing capabilities as the Regular Cab with the dual-rear-wheel drive configuration, but if you needed the extra cabin space, the Double Cab provides plenty of it.
One of the instrumental upgrades from the 2019 model year to the 2020 model year was an increase in the wheelbase up to 5.2-inches for the Crew Cab model, granting occupants more interior volume for passengers and cargo, and this is still a staple refinement for the 2021 model year of the Chevy Silverado 3500 HD. The Crew Cab offers additional hip, leg, and shoulder room within the 3500 HD's interior cabin thanks to the extended 158.94-inch wheelbase. If you need that extra passenger volume while also requiring the capabilities that only a heavy-duty Chevy pickup can provide, then the Crew Cab format is the optimal choice.
Special Perks for Special Editions
Available 10-way power driver and front passenger seats help define the comfort aspects of the interior, with additional amenities available with the 2021 model year special editions.
