A Trim Guide to the 2024 GMC Sierra 1500

When the Grabowsky brothers established the Grabowsky Motor Company in the early 1900s, it’s unlikely they envisioned their dream would continue to thrive for another 100+ years. The company changed hands and names a few years later to the General Motors Company; nevertheless, as it inches closer to its 125th birthday, it’s clear the Grabowskys were on to something all those years ago.

Today, GMC is known for its rugged and reliable lineup of SUVs and trucks, including the GMC Sierra 1500 for sale, which debuted in 1999. While there are some similarities between that truck and the truck you’ll find on dealership lots today—like the available three cab sizes and three bed lengths—there are many other things that have changed. So, let’s take a deep dive into the trims of the 2024 GMC Sierra 1500 to get the information you need to choose the right one for you.

The GMC Sierra 1500, Trim by Trim

Some key features of the 2024 GMC Sierra 1500 include best-in-class base torque, a max diesel towing capacity of 13,200, the availability of Super Cruise, best-in-class Crew Cab front headroom and legroom, and the inclusion of over forty inches of combined digital displays, which is also more than any other vehicle in its class.

You’ll find these features and more spread throughout eight trim levels, ranging from the base Pro to the top-of-the-line Denali Ultimate, which is an effective blend of luxury, performance, and rugged durability. Those eight trims are also divided into three categories, with the two off-road-ready AT4 trims and two luxury Denali trims separated from what might be considered the four prosaic trims.

The Pro, SLE, Elevation, & SLT

The Pro, SLE, Elevation, and SLT trim levels are considered your everyday driving trims. That doesn’t mean they don’t offer comfort and convenience or the ability to head off-road; it simply means they’re more balanced, ensuring you can enjoy whatever and wherever the road takes you. Regardless, the four share many similarities, which is another reason to review them as a group.

The first three—the Pro, SLE, and Elevation—have a standard 2.7L TurboMax engine that delivers up to 310 hp and 430 lb-ft of torque. Meanwhile, the SLT starts with the 5.3L EcoTec3 V8 engine, which is also available for the other three trims. For the SLE, Elevation, and SLT, you might also opt for the 3.0L Duramax Turbo-Diesel engine. Finally, the SLT also offers a 6.2L EcoTec3 V8 engine. In other words, you have four different engine options depending on which trim you choose.

You’ll also find the GMC Multi-Pro tailgate standard on the SLE, Elevation, and SLT. This six-function tailgate optimizes your truck’s capabilities by making loading and unloading easier, as well as giving you greater access to the cargo box thanks to the full-width step that can hold up to 375 lbs and the hand grab that gives you a leg up as you get into the back of the truck.

Another standout feature for these trims is the availability of the Max Trailering Package for all but the Pro. This package gives you increased towing and GCWR (Gross Combined Weight Rating), an automatic locking rear differential, an enhanced cooling radiator, revised shock tuning, trailer brake control, and more. A standard trailering package that includes things like Hitch Guidance, a trailering hitch platform, and a two-inch receiver hitch exists on all but the Pro level, as well, but it is at least available for the Pro.

You’ll also find a push-button start and the GMC Pro Safety suite standard across all four of these trims, the latter of which includes the following:

  • Forward Collision Alert: This system scans the road ahead to alert you of an impending collision with a vehicle or pedestrian.
  • Following Distance Indicator: This system ensures you stay at a safe distance from the vehicle in front of you.
  • Front Pedestrian Braking: When a pedestrian crosses into the roadway, this system applies braking to assist in preventing a collision.
  • Lane Keep Assist w/ Lane Departure Warning: This system ensures you stay in your lane, providing you with alerts if you sway too far from the center.
  • Automatic Emergency Braking: Working in conjunction with Front Collision Alert and Front Pedestrian Braking, this system gives you added confidence as you head down the road.
  • Buckle to Drive: With safety as a priority, this system ensures you’re buckled up before you head out for the day.
  • IntelliBeam: This system gives you the light you need without you having to worry about finding the high beams.

You’ll also find comfort in the available power driver’s seat, convenience and easy access to your favorite apps with the available 13.4-inch GMC Premium Infotainment System with Google Built-In, and functionality thanks to multiple USB charging ports, available rear under-seat storage, and more. Altogether, any of these four trims is a great option for your everyday driving needs.

The AT4 & AT4X

These two trims are also great for everyday use, but they’re primarily geared to those who want to hit the trails. For instance, the AT4X gives you both front and rear locking differentials, which is not offered on any other truck in this class. You’ll also find a factory-installed two-inch suspension lift and Multimatic DSSV Dampers on the AT4X.

Not only that, but the 13.4-inch GMC Infotainment System with Google Built-In, along with the 12.3-inch digital Multicolor Driver Information System, gives the dashboard a sleek and modern look while also giving you quick access to everything you need to make the drive more enjoyable. Additionally, both the AT4 and AT4X offer a standard 3.0L Duramax Turbo-Diesel engine with a ten-speed automatic transmission.

Some key features of the AT4 include the available CarbonPro composite bed, the two-speed Autotrac transfer case, and underbody skid plates. Meanwhile, you’ll enjoy an AEV stamped-steel front bumper with front winch capability and an AEV stamped boron steel front approach skid plate on the AT4X. Finally, the Selectable Traction Modes on both trims give you complete control, regardless of the terrain; these modes include Sport, Tour, Terrain, and available Off-Road and Tow/Haul modes.

The Denali & Denali Ultimate

Over the years, “Denali” has become synonymous with luxury, and the 2024 GMC Sierra 1500’s two Denali trims are the most luxurious ever. You’ll find the availability of hands-free driving thanks to Super Cruise, as well as over 40 inches of digital displays that keep you connected throughout the drive. Even better is that, if that drive lasts longer than just a trip to the store, you can also take advantage of the sixteen-way power front seats with a built-in massage feature. The Denali trims also give you the ability to haul more cargo than any other truck in its class.
