GMC’s Sierra 3500HD remains unchanged for 2023, as the most heavy-duty variant of the three-model Sierra truck range. Buyers have a choice of engines, bed lengths, cab configurations, trims, transmissions, drive modes and even the number of wheels fitted to their 3500HD.

Unlike other websites and magazines, our ratings are not based solely on a singular road test, but rather a more encompassing batch of criteria: quality, safety, comfort, performance, fuel economy, reliability history and value. When comparing vehicles using our Rating System, it's important to note that the rating earned by each vehicle correlates only to the models within its class. For example, a compact car cannot be compared to a SUV—They are different vehicles altogether.
You can interpret our ratings in the following way:
5-Star: Outstanding vehicle. Only the most exceptional vehicles achieve this rating.
4-Star: Very Good vehicle. Very good and close to being the best vehicle in its class.
3-Star: Good vehicle. Decent, but not quite the best. Often affordable, but lacking key features found in vehicles of the same class.
2-Star: Below average vehicle. Not recommended, and lacking attributes a car buyer would come to expect for the price.
1-Star: Poor vehicle. Simply does not deserve to be on the road.
2023 GMC Sierra 3500HD Overview
Choosing Your GMC Sierra 3500HD
The 2023 Sierra 3500HD range is as complex as its smaller sibling, with four body styles – Regular, Double and Crew Cab, all fitted with a Long Bed (except Crew Cab, where a Standard Bed is also available). You can specify dual rear wheels in both 2WD and 4WD configurations as a $1,200 option.
Entry to the 3500HD range starts at $44,195 including destination for the 2WD single rear wheel Pro in Regular Cab Long Bed guise with a gas engine. The other end of the pricing scale sees a sticker price of $86,245 applied to a six-wheeled AWD Denali Crew Cab Long Bed powered by a turbodiesel engine. In between, there are over a hundred different model configurations to choose between, but you’ll need a six-seater Crew Cab to unlock the three higher trim levels – SLT, AT4 and Denali.
The engine range in the 3500 HD is shared with its 2500HD stablemate. That means there’s a 6.6-liter V8 gas engine that produces 401 horsepower and 464 lb-ft of torque, supplied to two, four or six wheels through a six-speed automatic transmission. An identically sized turbodiesel unit generates 445 hp and 910 lb-ft, via a ten-speed auto box.

|6.6L Turbodiesel||445 hp||910 lb-ft|
Passenger and Cargo Capacity
The three-seater Regular Cab and six-seat Double Cab models are exclusively available with a 98-inch Long Bed, while the two-row Crew Cab can be specified with either this or an 82-inch Standard Bed.
Every 3500HD receives six airbags, Teen Driver and traction control, but you’ll be raiding the options list for anything else on Pro and SLE models. The latter does at least offer cruise control. Only top-range Denali models have standard safety features like park assist, forward collision alerts, HD surround vision or lane departure warning/change alerts, let alone emergency braking. Even by truck standards, that seems a long way behind the times.
The base Pro model is a throwback to a bygone age, with a seven-inch infotainment screen powering a six-speaker stereo with Bluetooth. That’s about it until you upgrade to SLE (with satellite radio and WiFi capabilities) or SLT (eight-inch infotainment system and wireless smartphone mirroring). Denali gets navigation, a Bose stereo and wireless device charging, though these options can be added to lesser trims as part of GMC’s extensive options list.
The most basic 3500HD comes with LED exterior lighting, 18-inch silver wheels and chrome bumpers. Inside, everything is manual, from the vinyl seat adjustment to the non-telescopic steering column tilt. You do get single-zone climate, power windows and door locks plus rear camera hitch guidance.
There are over 30 packages across the Sierra 3500HD range, with Pro’s recommended upgrades including the $615 Safety Confidence Pack. It contains cruise control, a color driver information center, automatic emergency braking and forward collision alert. The $890 Driver Alert Package I is also highly recommended, bundling in rear cross traffic and lane change/side blind zone alerts.
A power-locking six-function remote-release tailgate is one of SLE’s exterior highlights, alongside metallic grey wheels. Remote keyless entry facilitates access to a cabin featuring GMC Connected Services, carpets and a color driver information center.
The SLE Convenience Package blends ten-way power and lumbar for the heated driver’s seat, keyless open and start with dual zone climate with a heated steering wheel, for $2,255. You could also spend $890 on the Driver Alert Package II’s lane departure warning, automatic emergency braking, forward collision alert and distance indicator systems, combined with intelligent headlights.
Modest external differences on Crew Cab-only SLT models include cargo bed lighting, LED fog lights and turn signals, power adjustable and power-folding outside mirrors. Step inside using keyless entry, and you find 10-way power for the heated leather front outboard seats (including power lumbar for the driver), dual-zone climate, a heated steering wheel and wireless phone mirroring.
The two Driver Alert Packages remain available, alongside the $1,670 SLT Preferred Package, which combines a Bose stereo and navigation with wireless device charging and HD surround vision. The $1,500 Convenience Pack includes a power sliding rear window, ventilated front bucket seats and LED roof lamps.
AT4 rides into battle with skid plates and off-road suspension alongside Hill Descent Control and twin-tube shock absorbers. The front outboard bucket seats are ventilated and wrapped in perforated leather, while the rear outboards are heated.
Paying $1,475 for the Technology pack brings a 15-inch head-up display and eight-inch digital information center, plus a rear camera mirror. Alternatively, the $2,075 AT4 Preferred Package brings navigation and wireless charging, HD surround vision and a Bose audio system.
If the price hike to Denali models seems steep, it’s more than justified by the standard spec list. This is the only 3500HD to ride on 20-inch polished aluminum wheels with chrome assist steps and handles. It’s unique in having intelligent high beams, a power sliding rear window, LED roof lights and navigation, plus a Bose stereo.
You can spend $1,275 on the Technology package’s head-up display and rear camera mirror, or upgrade to the $2,270 Ultimate Package which adds these features alongside a sunroof.
The mind-range SLT model looks and feels more refined than the sparsely equipped lower models, but you’ll need to add a few options packs to bring its safety up to modern standards. Denali includes all these features as standard, but at a considerable premium.
