American Expedition Vehicles (AEV) and GMC have collaborated again, this time with a concept truck called the AEV GMC Sierra Grande. This is a bulked-up flatbed, two-door HD truck that looks incredibly expedition-ready. But don’t start calling your GMC dealer just yet, this is only a concept build right now. Unlike other GMC\/AEV collaborations, it isn’t slated to enter production.<\/p>\n
<\/p>\n
Essentially, this truck is from the GMC Sierra 2500HD AT4X AEV Edition. It’s based on the AEV Prospector XL combined with a long-bed GMC Sierra 2500 HD with a Duramax diesel engine and a regular cab layout. Neither one of these vehicles exists by itself, so the combination is a true unicorn that can’t be found anywhere outside of the upcoming 2023 SEMA Show, where it will be on display at the AEV booth.<\/p>\n
The combo has been dubbed the Sierra Grande, and it uses a lot of parts from the aforementioned 2024 GMC Sierra 2500HD AT4X AEV Edition, but that truck only comes in a four-door crew cab layout. Some of the parts used include a stamped-steel front bumper, underbody skid-plate protection, rear suspension, Multimatic DSSV dampers, and the same control arms and steering knuckles.<\/p>\n
The AT4X parts mean that the base truck has a 1.5-inch lift over the regular GMC 2500 HD and it also means that it can fit 35-inch tires. However, the Sierra Grande manages 40-inch BFG tires with AEV HighMark fender flares.<\/p>\n
Instead of modifying the bed, the AEV crew installed an eight-foot aluminum tray flatbed that includes a spare tire mount near the cab. This gives the Sierra Grande a distinct overlanding aesthetic that stands out. Additional parts include an AEV brush guard decked out with four AEV 7000-series off-road lights, plus an AEV snorkel and a GM Performance front winch rated at 12,500 pounds.<\/p>\n
The mods don’t end there. The Sierra Grande also adds a custom AEV rear bumper with an extra rear winch that is rated for 9,500 pounds. The truck is outfitted in custom green paint that has a slight gray cast to it. A plethora of Sierra Grande, AEV, and AT4X badges decorate various areas on the truck.<\/p>\n
One big takeaway from this truck is that the new GMC HD models can indeed run 40-inch tires, but you, unfortunately, won’t be finding this as a factory offering at your GMC dealer<\/strong><\/a>.<\/p>\n However, the truck that the Sierra Grande is based on should be arriving at your GMC dealer soon. It may already be there. The truck<\/strong><\/a> was announced earlier in the year and was slated for arrival at dealers in the fall. It may not be as monstrous as the Sierra Grande, but it’s still a pretty capable and aggressive truck.<\/p>\n Pricing for the AEV Edition trucks wasn’t available earlier in the year, but you can check with your GMC dealer for the most current numbers.<\/p>\n <\/p>\n2024 GMC Sierra HD AT4X and AT4X AEV Edition At Dealers Now<\/h2>\n
