If you need a heavy-duty pickup truck for work or recreation, you can’t go wrong with the 2023 GMC Sierra 2500 HD. It’s a little more compact than the 3500 version while still offering significant power and versatility. Even better is that this model is available in five trim levels, which is just enough to provide variety without making your purchase overwhelming. Here at Seminole Chevrolet GMC, we’re ready to make your decision even easier by comparing the five 2023 GMC Sierra 2500 HD trims. Read on to discover their key features and learn which trim suits your preferences.
2023 GMC Sierra 2500 HD Pro

2023 GMC Sierra 2500 HD
As the new 2023 GMC Sierra 2500 HD’s most basic trim, the Pro has key features that make it an ideal work truck. It has the same standard 6.6-liter V-8 gas engine that the other trims have, meaning it can produce up to 401 horsepower and 464 lb-feet of torque. If you prefer a diesel engine, you can opt for the 6.6-liter Duramax Turbo-Diesel V-8 engine to get up to 445 horsepower and 910 lb-feet of torque. Another standard feature is the six-speed, heavy-duty electronically controlled automatic transmission, though you can opt for Allison 10-speed automatic transmission.
The Pro has available integrated power take-off (PTO) for the Allison transmission, which features smooth shifting performance and auto grade braking. As a basic trim, it lacks the standard features you get with other trim levels. For instance, the Pro is the only trim that has the GMC MultiPro tailgate as an available feature instead of a standard feature. It includes six distinct functions that streamline the loading and unloading of cargo. For instance, the inner gate folds down for easy access while the load stop prevents items from sliding out of the bed.
2023 GMC Sierra 2500 HD SLE
While the SLE is still one of the more basic 2023 GMC Sierra 2500 HD trims, subtle upgrades allow it to stand out from the Pro. You’ll appreciate the upgrade from standard 17-inch steel-painted silver wheels to 17-inch aluminum wheels. Other key exterior features include black power-adjustable vertical trailering mirrors, body-color door handles, deep-tinted glass, and stainless-steel beltline moldings. When you look inside, you’ll notice that it upgrades the Pro’s 3.5-inch diagonal monographic Driver Information Center to a 4.2-inch diagonal color Driver Information Center.
Similar to the Pro, the SLE has several standard safety features for your peace of mind, such as hitch guidance, LED daytime running lamps, a rear vision camera, and a tire pressure monitoring system. You’ll appreciate the OnStar and GMC Connected Services capability, which is available for the SLE and the trim levels above it. These trims also include three years of these services to help you understand their full value. An available camera in the center high mount stop lamp (CHMSL) provides an elevated view of the truck bed from the back of the cab. The image appears on the infotainment display so you can quickly check cargo.
2023 GMC Sierra 2500 HD SLT
As a mid-level trim, the 2023 GMC Sierra 2500 HD SLT continues to add features to offer drivers and their passengers a more comfortable ride. Dual-zone automatic climate control is standard and ensures the system automatically maintains the selected temperatures for the driver and front passenger. Another standard feature is remote start, which allows you to start the truck from a distance so you can step into the perfect temperature. When you have the SLT’s keyless open and start fob in your possession, you can lock the doors and start the truck without taking the fob out of your pocket.
You might want to opt for the SLT trim if you want to streamline the process of hitching your trailer. Hitch guidance with hitch view is a standard feature that displays a guideline on the rear vision camera view when you’re reversing. You can also use this camera to check the trailer connection.
2023 GMC Sierra 2500 HD AT4
Those planning on trucking through especially rough terrains might opt for the AT4 trim. One example of a feature that helps this truck withstand the elements is the standard skid plates. These metal sheets help protect the front underbody, oil pan, differential case, and transfer case from the toughest conditions. The standard Autotrac two-speed transfer case with push-button controls allows you to switch between two- and four-wheel drive, making it easy to customize the amount of power your wheels get.
Some drivers choose to upgrade the AT4 by opting for the Premium Plus package. Key exterior features include 20-inch machined aluminum wheels with high-gloss black accents and a high-clearance step for easy entry. Additionally, you can choose from HD surround vision with two trailer view camera provisions, a multicolor 15-inch diagonal head-up display, and a Bose premium sound system.
2023 GMC Sierra 2500 HD Denali
The most advanced 2023 GMC Sierra 2500 HD trim is the Denali. With a starting manufacturer’s suggested retail price (MSRP) that’s nearly $25,000 more than the Pro’s MSRP, the Denali has several premium features that justify the cost. For instance, consider its standard HD surround vision that uses multiple cameras to display a digital overhead image of your truck’s surroundings. The standard universal home remote feature embodies convenience by activating devices like garage door openers and security systems from inside your truck.
If you want to customize your 2023 GMC Sierra 2500 HD even further, you can opt for a Denali Black Diamond Edition or Ultimate package. The former includes key features like trailer tire pressure monitor sensors and an auxiliary trailer camera. Those who get the Ultimate package can enjoy a multicolor 15-inch diagonal head-up display and power sunroof.
Whether you’re looking for something simple like the Pro or something decked out like the Denali, the 2023 GMC Sierra 2500 HD is sure to have a trim that suits your needs.
