How the 2022 Sierra AT4X & AT4 Trims are Different

If GMC already had a premium off-road-ready platform like the AT4 in production, what is the purpose of adding the AT4X to the lineup? Our team of product experts thought long and hard about this very question for quite a while. Once they learned more about the trucks, the key differences became clear. The new AT4X variant of the 2022 GMC Sierra 1500 takes advantage of new technology and components, while also providing a better ownership experience.

When the 2022 GMC Sierra 1500 AT4X goes on sale, it will offer uniquely tuned springs for increased front and rear suspension travel versus the AT4. Also, the chassis has been tweaked to be more conducive for off-road driving. Finally, a steel transfer case skid plate has been added to protect sensitive systems under the truck from rocks and other obstacles.

What are the Features of the 2022 GMC Sierra 1500 AT4X?

Other truck manufacturers have built off-road-themed pickup trucks. To be honest, some of them are pretty good. However, those same models tend to be too focused on off-road performance, meaning that on-road handling suffers. The 2022 GMC Sierra AT4X better bridges that gap, offering a platform that delivers on what it promises regardless of what kind of road surface it is using. Some of the impressive equipment included with the new AT4X trim will include:

  • Front/rear e-locking differentials (a class first)
  • Sierra-first use of Multimatic DSSV spool-valve dampers
  • Heated/ventilated 16-way power-adjustable seats
  • Front seat massage function
  • Steel transfer case skid plate
  • Available rocker protection
  • Obsidian Rush interior featuring full-grain leather upholstery
  • Authentic Vanta ash wood panels

What are the Features of the 2022 GMC Sierra 1500 AT4?

The GMC Sierra AT4 set the bar high for premium off-road-ready pickup trucks. Even without the enhancements found on the new AT4X, the original AT4 is a strong performer with the follower standard and available equipment:

  • Standard 2-inch lift with Rancho® monotube shocks
  • Two-speed AutoTrac transfer case
  • Automatic locking rear differential
  • Heated/ventilated front seats
  • Available CarbonPro cargo bed

Which Engines Are Available with the AT4X and AT4?

Every AT4X is available with one option, the naturally aspirated 6.2-litre, V-8 engine attached to a 10-speed automatic transmission. It will make up to 420 horsepower. Ernie Dean customers opting for the AT4 will get the 3.0-litre, Duramax Turbo Diesel engine as standard equipment. The 6.2-litre is available as an option.
