AEV works its magic to give GMC a beefier and even more off-road-capable Sierra 1500 AT4X pickup.
GMC is working with American Expedition Vehicles to make the 2023 Sierra 1500 AT4X even more capable. GMC calls it the most capable factory off-road Sierra ever thanks to the new AEV front and rear bumpers, skid plates, and upgraded wheels and tires. Plus it has more changes, both cosmetic and functional, that help make the Sierra AT4X AEV Edition stand out.
When GMC launched its AT4 trim level on the Sierra in 2019, the idea was a truck that offered some of the full-zoot Denali’s luxury appointments with less flash and more off-road capability. A truck that was better suited to gravel roads and the cottage driveway than a blinged-out, shiny chrome Denali truck.
AT4X Gets Short Run as Top Sierra

It didn’t take GMC long to outdo itself by debuting the Sierra AT4X. It’s an upgrade that gave the Sierra even more capability from the factory, including Multimatic’s magical DSSV spool-valve dampers. The AT4X was introduced just late last year along with Sierra’s 2022 facelift.
The Sierra 1500 AT4X gets a standard 6.2L V8 and 10-speed automatic. New springs with the DSSV dampers mean 2 inches more suspension travel in the front and an inch in the rear. There are electronic-locking differentials on both axles, a larger transfer case shield, and some interior upgrades like ash wood trim that you’re just going to coat with dust and mud anyway.
