GMC AT4 Sub-Brand Celebrates 5th Anniversary

GMC is celebrating this year, marking not only the 25th anniversary of the luxury-oriented Denali sub-brand, but also the 5th anniversary of the off-road-oriented AT4 sub-brand. Offering a wealth of equipment specifically designed to hit the local trails, GMC’s AT4 models are among its most popular, with the range expanding considerably over the last five years. Looking ahead, that momentum isn’t expected to slow down any time soon.

The 2019 GMC Sierra 1500 AT4.

GMC’s AT4 sub-brand launched in conjunction with the 2019 GMC Sierra 1500, offering customers a two-inch factory-installed suspension lift, off-road-tuned Rancho monotube shocks, exclusive 18-inch wheels wrapped in all-terrain tires, Hill Descent Control, the Traction Select System, red vertical recovery hooks, AT4-specific interior trim, and more.

The 2020 GMC Acadia was the second model to receive a new AT4 variant, followed by the 2020 GMC Sierra HD. Interestingly, all three models (GMC Sierra 1500, GMC Acadia, and GMC Sierra HD) also offered an All Terrain variant, which the AT4 line essentially replaced.

By August of the 2019 calendar year, GMC announced that every model in its lineup would offer an AT4 variant by the 2021 calendar year. These included the 2021 GMC Canyon, the 2021 GMC Yukon, and the 2022 GMC Terrain. The all-electric 2025 GMC Sierra EV is also expected to offer an AT4 variant, eventually.

Building on the success of its AT4 lineup, GMC later launched its AT4X models, which one-upped the AT4 models with next-level off-road capabilities. The AT4X line launched in conjunction with the refreshed 2022 GMC Sierra 1500 (2022.5 interim model year), offering customers unique Multimatic DSSV spool-valve dampers with increased suspension travel, 18-inch wheels wrapped in Goodyear Wrangler DuraTrac Mud-Terrain tires, standard skid plates, a two-speed transfer case with selectable driving modes, front and rear e-locking differentials, and more.

The 2023 GMC Canyon was the next model to offer an AT4X variant, followed by the 2024 GMC Sierra HD.

So far, the AT4 trim lineup has proven to be a winning formula for GMC, with Big Red reporting its highest annual volume for AT4 trims at 19 percent for the 2023 calendar year, riding a 6.5-percent overall increase in retail sales in the U.S. No doubt GMC will look to continue that momentum into 2024.

  2. Dont see the need for sub branding. GMC is suppossed to be the best GM has to offer be it what ever you desire or need. Leave the sub branding title to those who like the often ugly unecessary stick on labels to others. I like the nice simple chrome lables that separate the mainly soft ride and comfort from the harsh off road suspension modifications to a simple chrome label. I am very aware that some are impressed or love off road stick on labels. My plain chrome plated 4X4 label is all I need or want. Labels fade and eventually peal off or get damaged in car washing. If you are impressed with labels, then get them.

    1. Retract my previous comments on sub branding of GMC trucks. The big stick on labels were what I don’t like or are impressed with. The smaller CHROME labels with AT4 or X what ever level you have are very attrictive and do serve a purpose. The biq stick on labels on the rear quarter panels are what are not attrictive to me.

  3. Wait! FYI 2014 GMC offered the All-Terrain package, which consisted of Z71 SLT with All-Terrain badging. Then 2019 AT4 was adapted utilizing the short version. Basically, the same but different marketing. Still have my 2014 GMC Sierra coming up on 10 years this June. So far, it’s been a great truck, after I replaced the Rancho/Tenneco Shocks with Bilstein 6112 to level the stance and better ride control, among other upgrades.
