Purpose-Driven Power 

The Silverado 3500 HD has two available powertrains. The standard engine is a gasoline-powered 6.6-liter V8 with a 3.73 rear axle ratio. It is matched with an Allison 10-speed electronically controlled automatic transmission with overdrive, tow/haul mode, and auto grade braking, and the powertrain churns out 401 horsepower and 464 foot-pounds of hard-working torque.

For those who prefer the smooth, reliable power of a diesel engine, there’s an available 6.6-liter Duramax Turbo-Diesel V8 with added features like a 3.42 rear axle ratio, engine block heater, exhaust brake, and engine run-after feature for enhanced cooling. It’s also paired with an Allison 10-speed automatic transmission, and together they create 470 horsepower and 975 foot-pounds of torque. The 3500 HD is available with RWD and 4WD drivetrains.

Heavy-Duty Hauling Capability

The 3500 HD puts its heavy-duty power to good use with towing and payload capacities that get the job done. The 6.6-foot standard Durabed comes with 12 built-in cargo tie downs, and it offers 69.5 cubic feet of cargo volume and can carry up to a maximum payload capacity of 7,442 pounds, depending on engine, drivetrain, and equipment selections.

The Silverado 3500 HD has the towing power to move even heavier loads, as it is rated for a maximum towing capacity of up to 36,000 pounds with the proper equipment and features. Towing is streamlined by the 3500 HD’s available trailering amenities, which include an in-vehicle trailering app, outdoor power-adjustable vertical trailering mirrors, hitch guidance, a hitch view camera, an integrated brake controller, and a trailer side blind zone alert.

Impressive Lineup of Technology Features   

The safety features in the Silverado 3500 HD help ensure that drivers and their crews arrive safely, no matter the driving conditions. For example, it has the StabiliTrak electronic stability control system for peak traction and handling. It also includes standard driver assistance features like automatic emergency braking, an HD rear vision camera, lane departure warning, forward collision alert, front pedestrian braking, and a tire pressure monitoring system.

The infotainment features in the 3500 HD help drivers take connectivity of the office to any jobsite. Those features include Chevrolet Connected Access, OnStar Basics, a 6-speaker audio system, a 3.5-inch driver information center, multiple charging and data ports, Wi-Fi hotspot capability, a 7-inch color multi-touch display, and the Chevrolet Infotainment 3 system with Google built in.
