Built to take on outsized loads with ease, this full-size pickup also has plenty of luxury features in tow.

Five trim variations offer something for everyone so explore what's available today.


Compare the Sierra 3500HD Pro vs SLE Trims. What is the difference?

With a starting MSRP of less than $43,000, the Sierra 3500HD’s Pro trim is your least expensive option. Although the Pro trim may not be as plush, it’s best for drivers who need a dedicated work truck. They’ll love this pickup’s tough-nosed design.

Like the rest of the range, the Sierra 3500HD Pro receives a gasoline V8 engine as standard equipment. It manages to push out a tad over 400 horsepower. A six-speed auto transmission is responsible for directing the available muscle to the wheels. This powertrain packs enough brawn for most towing jobs.

Drivers who need peak towing power can opt for GMC’s Duramax turbo-diesel engine. It’s rated to churn out 445 horsepower and in excess of 900 lb-ft of torque. A 10-speed Allison transmission, which is specially tweaked for heavy-duty applications, comes along with the diesel engine.

The federal government does not rate the heavy-duty Sierra 3500HD’s fuel economy. Nevertheless, many owners report averaging a combined 15 mpg. Drivers who spend a lot of time on the freeway will find the diesel-powered 3500HD to be more efficient overall.

The majority of Sierra 3500HD Pro buyers will have no issues with the pickup’s rear-wheel-drive layout. When the tires begin to slip, an automatic locking rear differential engages to help improve grip. An optional 4X4 system further improves traction.

This base model goes without any fancy appearance upgrades. However, full LED exterior lights do make the truck look modern. A massive chrome bumper with integrated tow hooks gives the truck’s front fascia a bolder look. To make it a bit less challenging to load cargo into the bed, GMC equips the pickup with a corner-step rear bumper. The Pro trim’s steel wheels can better withstand harsh environments.

Opting for the diesel engine also brings a high-performance hood. Its built-in air induction system helps optimize power output. Manual trailering mirrors come standard. Several exterior color options are available.

Passengers shouldn’t expect the Pro trim’s interior to be luxurious. Its cabin is designed for durability. Vinyl flooring and a urethane-covered steering wheel help the truck to handle the everyday grind. To cut costs, GMC equips this trim with manual windows and locks. Non-powered front seats also come standard. Three are three cab sizes: Regular, Double, and Crew.

Drivers can enjoy a modern GMC multimedia system, which features a standard 7.0-inch color touch display. It provides today’s most desirable infotainment features. Highlights include Apple CarPlay/Android Auto smartphone pairing and Bluetooth connectivity. Although the standard audio system isn’t powerful, it will provide some entertainment. Two USB ports, a 3.5-inch driver info display, and a 112-volt power outlet are also standard items.

Mandated safety features, such as a rearview camera and electronic stability control, are found on every version of the Sierra 3500HD. To obtain more advanced safety technologies, buyers must select one of the Pro trim’s optional packages.

GMC’s Driver Alert Package I adds a valuable Lane Change Alert system. It gives drivers the green light to move over to the next lane. Blind-spot monitoring and parking sensors are also part of the package.

Another safety-enhancing upgrade is the Driver Alert Package II. When traveling at speeds below 50 mph, its auto emergency braking system further reduces the likelihood of a crash. This package also gains lane departure alert and automatic high beams.

For drivers who want to further modernize the Pro trim, GMC offers a Convenience Package. While a cruise control system enables drivers to set highway speeds, remote keyless entry enhances security. Other upgrades include full-power interior accessories, an EZ Lift power lock-and-release tailgate, and a defogger for the rear window. A spray-on bedliner and satellite radio are standalone options.

A step above the Pro trim is the SLE trim. It enables drivers to experience greater comfort and more style. Prices start at nearly $48,000.

To give the Sierra 3500HD SLE a less bland look, GMC equips it with 17-inch alloy wheels. Heated trailering mirrors prepare the pickup for cold weather. Another useful feature is GMC’s flexible MultiPro tailgate. It can be used as an outdoor work surface, bed step, load stop, and more.

When moving up to the SLE trim, buyers will receive an excellent OnStar communications system. This system enables drivers to reach emergency roadside assistance at any time of the day. It also allows you to remotely check certain vehicle information, including tire pressure and fuel level. Another big feature is the OnStar system’s built-in Wi-Fi hotspot.

An integrated trailer-brake control feature enables drivers to tow with greater confidence. Carpeted flooring makes the interior look more premium. Other standard equipment includes a larger driver information screen, a wrapped steering wheel, power windows, and remote keyless entry.

Aside from the previously mentioned Driver Alert packages, this trim is also eligible for a SLE Convenience Package. The combination of a 10-way power driver’s seat and a tilt-and-telescopic steering wheel make it easier to obtain a pleasing driving position. Meanwhile, remote start and heated front seats improve cold-weather comfort. Dual-zone automatic temperature control and push-button start are also included.

Drivers who desire an upgraded infotainment system should consider the SLE Preferred Package. It steps up to a larger 8.0-inch touchscreen. Satellite radio and a 120-volt bed outlet are included as well.

Compare the Sierra 3500HD SLE vs SLT Trim Levels. What is the difference?

The Sierra 3500HD SLT definitely looks and feels like a more luxurious pickup truck. However, it's not available as a regular cab. Buyers can choose between Double Cab and roomier Crew Cab body styles.

Larger 18-inch alloy wheels give the truck a slightly more upscale look. LED fog lights and a bed-integrated 120-volt power outlet are added to the truck as well. Several more creature comforts come standard. Notable highlights include 10-way power front seats with heating modes, a tilt-and-telescopic steering wheel, dual-zone auto climate control, and a heated steering wheel.

Upon stepping up to the SLT trim trim, GMC enhances the infotainment system by adding wireless smartphone integration. When traveling after dark, an auto-dimming rearview mirror helps prevent the driver from being distracted by headlight glare. Just a few of the other perks include remote start, a defogger for the back window, and extra USB ports.

Another big upgrade is GMC’s Hitch Guidance with Hitch View technology. It essentially functions as a spotter when attaching a trailer. The driver’s job will be a lot less demanding.

To experience more luxury, select the SLT Convenience Package. It further dials up the comfort level by adding bucket seats and a cooling function for the front seats. A power-sliding back window and a HomeLink transceiver also come in the package.

Compare the Sierra 3500HD SLE vs AT4 Trim. What is the difference?

No other Sierra 3500HD trim is more rugged than the AT4 trim. It’s geared towards drivers who need a more formidable off-road machine. The Sierra 3500HD AT4’s standard 4WD system features an Autotrac 2-speed transfer case, which enables drivers to shift to low-range gearing when maximum grip is needed. Hill-descent control, trail-ready shocks, and extra undercarriage protection also help this trim to conquer more daunting terrain.

Exclusive styling treatments, such as red tow hooks and black chrome accents, help give the Sierra 3500HD AT4 trim a unique look. Trim-specific wheels add to the truck’s cool appearance. A spray-on bedliner provides an extra degree of protection when hauling loads.

On the inside, there are premium floor protectors. The front bucket seats receive standard heating and cooling modes. Heated rear seats and a center console are also found on this more adventurous trim.

An AT4 Preferred Package is optional. Its 360-degree camera system with Transparent Trailer View gives drivers an extra set of eyes. A bed-view camera further enhances visibility. To help make the package more appealing, GMC includes a Bose premium audio system and an upgraded infotainment system with navigation.

Compare the Sierra 3500HD AT4 vs Denali. What is the difference?

Featuring perforated leather upholstery and brushed aluminum interior accents, the Denali trim is the lineup’s preferred choice among luxury car fans. It receives a 8.0-inch digital driving display and wireless phone charging as standard equipment. An important safety feature is the Denali trim’s Safety Alert Seat. If one of the safety systems detects imminent danger, this innovative seat will help warn the driver by vibrating. Both of the previously optional Driver Alert packages come standard on the Sierra 3500HD Denali.

The Denali trim’s exterior features several chrome details. A special grille and 20-inch chrome wheels also give the truck a high-end appearance.

While the Denali trim is already loaded with a boatload of premium amenities, some buyers will want the available Technology package. While the package’s Rear Camera Mirror minimizes blind spots, a 15.0-inch head-up display makes your speed and navigation directions easier to view. Meanwhile, power-retracting assist steps and a sunroof come with the optional Denali Ultimate package.

For folks who really want to make a grand entrance, GMC offers the Denali Black Diamond Edition package. Its gloss-black wheels and Ebony Twilight Metallic paint job create an eye-catching look. A Kicker audio system with tailgate speakers makes this package more exciting. The previously mentioned power-retracting assist steps and a sunroof are included.


Final Thoughts

Standard features include a smartphone-friendly infotainment screen, LED exterior lights, and vinyl flooring.

Serious off-roaders will appreciate the Sierra 3500HD AT4’s rugged hardware. It’s the best trim for facing adverse terrain. Remember, an upgraded 4WD system comes standard. Creature comforts include heated/cooled front bucket seats and heated rear seats.
