What's New for 2019
The 2019 GMC Sierra 3500HD carries into 2019 with no significant changes.
Choosing Your Sierra 3500HD
Every Sierra 3500HD features the truck’s largest configuration, the crew cab, with four true doors and then offers a whole range of bed sizes, engines, and drivetrains. When properly equipped, the payload and towing capabilities are significantly greater than its “medium duty” twin, the Sierra 2500HD.
The standard-length box, at 6.5-feet, can be swapped for an 8.0-foot-long box for $200. Select the dual-rear-wheel configuration for another $600, available only with the long bed, and the payload capacity climbs from 3,758 to 6,655 pounds, while the towing capacity also increases from 17,500 to 23,100 pounds. The four-wheel-drive system is available on all trims and configures for $3,000 and includes a transfer case and additional underbody protection.
The base engine is a 6.0-liter V8 that develops 360 horsepower and 380 pound-feet of torque and is available only paired to a six-speed automatic transmission. While that power is certainly impressive, the optional 6.6-liter turbodiesel V8 engine generates an outrageous amount of power, achieving 445 hp and 910 lb-ft of torque. This engine is part of a package that also includes an Allison-branded six-speed-automatic transmission, exhaust brake, and block heater.
The Sierra 3500HD’s lineup consists of four trim levels:
