How Much Does a 2018 GMC Sierra 3500 Cost?

The 2018 GMC Sierra 3500HD comes in a wide variety of trim levels, body styles and configurations. There are Regular, Extended and Crew Cabs, along with regular beds and long beds, gasoline and diesel engines and 2- and 4-wheel drive. Drivers can also choose between two rear wheels or four (a "dually"), depending on their desired payload capacity.

As for trim levels, the Sierra starts with a base model simply called the Sierra ($42,390) that actually comes pretty well-equipped. Standard features include 17-inch steel wheels, an automatic locking rear differential, xenon headlights, LED running/accent lights, power locks, manual windows, cruise control, a front beach seat, a tilt-only steering wheel, a backup camera, a USB port, an auxiliary audio jack and a 6-speaker sound system. Also standard is a 7-in IntelliLink touchscreen that brings with it Bluetooth and Pandora. There is the choice of cloth or vinyl upholstery.

Next up is the Sierra SLE ($49,090), which adds alloy wheels, rear privacy glass, full power accessories, keyless entry and a remote-locking tailgate, power windows, a leather-wrapped steering wheel, a CD player, HD Radio and an 8-in touchscreen.

Above the SLE is the upscale SLT ($54,190), which adds 18-in wheels, power-folding mirrors, heated 8-way power front seats, driver memory settings, power-adjustable pedals, a tilt-telescopic steering wheel, dual-zone automatic climate control and remote ignition.

To the SLT (4WD/Crew Cab/single rear wheel), you can add the All-Terrain HD package. Available only as a Crew Cab, it adds all-terrain tires, the "Z71" off-road suspension, underbody protection, side steps, a spray-on bedliner, body-color bumper trim, parking sensors and a heated steering wheel. The Z71 suspension can be ordered separately on the SLE and SLT, though again, not with dual rear wheels.

There's also the popular range-topping Sierra Denali trim ($59,190). Available only as a Crew Cab, it adds unique styling elements, including a new grille design, 20-in wheels, side steps, a power-sliding rear window, parking sensors, ventilated front seats, a heated steering wheel, a navigation system, wireless smartphone charging and a Bose sound system.

In terms of options, the Sierra 2500HD offers quite a few, including upper trim level features being available on lower trims. In addition to the Duramax turbodiesel engine, Sierra buyers can also opt for a heavy-duty trailer package, a snow plow prep package and high-tech safety features, including a forward-collision alert system and a lane-departure warning system that vibrates the driver's seat should you drift from your lane.
