2019 GMC Sierra 2500HD Specs, Release Dates, Prices

If you need a truck that can pull heavy trailers, carry up to six passengers in the comfort of a luxury SUV, or a combination of both, the 2019 GMC Sierra 2500HD will deliver. While the Sierra 1500 was completely redesigned for 2019, the Sierra 2500HD was largely unchanged.

That means you still have a choice of a healthy 6.0-liter V8 or a very powerful 6.6-liter turbodiesel. The maximum towing capacity is more than 14,000 pounds, and the payload capacity reaches more than 3,200 pounds. Indeed this is not the highest number in the class, but they surely close and very respectable.
Inside, the 2019 GMC Sierra 2500HD features a handsome cabin highlighted by spacious passenger room and an easy-to-use infotainment system with Android Auto and Apple CarPlay smartphone integration. And like many of today’s cars and trucks, the GMC 2500HD also offers a suite of active driver aids, including parking sensors, lane departure warning and forward collision warning.

NEW FOR 2019

  • Regular-cab Sierra 2500HD is no longer available
  • Short-bed Double Cab model removed from the 2500HD lineup
  • PRICING: base $41,090; SLE $45,890; SLT $53,290; Denali $59,390


The 2018 GMC Sierra 2500HD is a heavy-duty pickup truck available in four trim levels: base, SLE, SLT and Denali. There are two configurations: double cab and crew cab with either a standard bed (6 feet 5 inches) or a long bed (8 feet 2 inches).

The base Sierra comes standard with 17-inch steel wheels, an automatic-locking rear differential, xenon headlights, LED daytime running lights, a choice of cloth or vinyl upholstery, a 40/20/40-split front bench with a fold-down center armrest, a 60/40-split folding rear seat, a rearview camera, power door locks, cruise control, a tilt-only steering wheel, a 7-inch touchscreen, two USB ports, Apple CarPlay and Android Auto compatibility, Bluetooth, and a six-speaker sound system. Optional tech equipment includes OnStar with a 4G LTE Wi-Fi hotspot and satellite radio.

The SLE gets the base trim’s optional tech features along with 17-inch alloy wheels, tinted rear windows, a remote-locking EZ Lift and Lower tailgate, LED cargo box illumination, remote keyless entry, carpeting, a leather-wrapped steering wheel, and an upgraded 8-inch central touchscreen.

The Sierra 2500HD SLT only available in a crew-cab configuration and adds 18-inch wheels, additional chrome trim, foglights, power-folding mirrors, dual-zone automatic climate control, leather upholstery, power-adjustable and heated front seats, driver-seat memory settings, power-adjustable pedals, a tilt-and-telescoping steering wheel, an auto-dimming rearview mirror, remote ignition, and a 110-volt household-style power outlet.

The top trim Denali get you even more chrome on the outside, 20-inch wheels, a spray-in bedliner, a power-sliding rear window defogger, front and rear parking sensors, a navigation system, wireless phone charging, a Bose audio system, a configurable 8-inch driver information display, upgraded interior trim, ventilated front seats, and a heated steering wheel.

The Driver Alert package adds front and rear parking sensors, lane departure warning, forward collision warning and a safety-alert driver seat. The Z71 suspension package adds hill descent control, skid plates, specially tuned shock absorbers and unique styling tweaks. Also available (on the SLT only) is the All Terrain HD package, which adds off-road tires, the spray-in bedliner, a skid plate, the Z71 suspension and a heated steering wheel.

Most of the upper trims features can be added to the lower trim levels as options. Depending on trim level, other options include different axle ratios, a bed storage box, various tonneau covers, trailering mirrors, a sunroof, a gooseneck/fifth-wheel trailering prep package, and a rear-seat entertainment system.


Space is bountiful in the 2019 GMC Sierra 2500HD Crew Cab, which promises expansive front-seat space. When fitted with a bench seat, three adults can fit up front. Basic interior design is shared with Chevrolet’s Silverado.

Front bucket seats have flat cushions with low, but firm, bolsters and comfortable for long journeys. Headroom has grown, compared to the previous generation. The center console can hold a laptop, and most Sierras offer readily-accessible charge points. Rear seats are more accommodating than before, with nearly 3 additional inches of legroom. Crew-cab back seats also benefit from wide door openings. Seat bottoms flip up to expand storage space. Abundant sound-deadening keeps the cabin relatively hushed.

It’s hard to believe the Denali version is supposedly a work truck. From the inside, aluminum trim on the instrument panel, perforated leather seats with contrasting stitching, and a heated steering wheel convey the air of an upscale SUV. But even the most unadorned model doesn’t feel like drudgery, thanks to things like a 7-inch touch screen for the infotainment system, rearview camera, air conditioning, powered windows/locks, and a split-folding front-bench seat. The trim levels in between, SLE and SLT, pile on amenities like dual-zone climate control and power-adjustable pedals.

The 2019 GMC Sierra 2500HD cargo bed adopted some cutting-edge construction to boost usable space. Depending on configuration, GMC offers a dozen tie-downs, a cast-in step, and LED bed lighting.


The standard engine for the 2019 GMC Sierra 2500HD is a 6.0-liter gasoline V8. There’s a version that uses compressed natural gas (CNG) producing 360 hp and 380 lb-ft of torque, but the regular version is tough enough. The real power, though, is the optional 6.6-liter V8 turbodiesel developing 445 horsepower and 910 lb-ft of torque. In common with many other big diesel engines, this one has an exhaust-braking feature, which is most welcome when driving downhill. Every engine option is paired with a 6-speed automatic transmission, but the diesel has one from the renowned Allison company. Rear-wheel drive is standard, with all-wheel drive as an option throughout. The Environmental Protection Agency (EPA) doesn’t provide fuel-economy estimates for this size of vehicle.
