GMC is doing the only cab pickup justice at SEMA this yr with an idea that dials up the off-road functionality and eventually scales again the variety of doorways. GMC partnered with AEV to develop the GMC Sierra Grande Concept, constructed off of a GMC Sierra 2500 HD in a single cab, lengthy mattress configuration. The completed product is a chassis cab truck with the proper variety of doorways for the gnarliest builds — simply two.
The of us at AEV primarily constructed a smaller Sierra HD AT4X by taking the suspension elements of the AT4X and putting in them right into a diesel-powered heavy obligation truck. The truck corrects the most important drawback with the GMC Sierra HD AT4X — the sheer measurement of it, which makes the truck much less adept at off-roading.
It’s not just like the GMC Sierra Grande is a compact truck, not by any means. The truck’s title means “big mountain range,” in spite of everything. But the construct is all about making it a succesful off-roader moderately than a roomy truck for use for towing. AEV describes the modifications, as follows:
Starting with a 2024 GMC Sierra 2500 HD in a daily cab, lengthy mattress configuration, AEV sourced the stamped metal entrance bumper from the Sierra HD AT4X AEV Edition and added a prototype brush guard for much more front-end safety. Additionally, AEV added (4) 7000 sequence off-road lights and a GM Performance/ComeUp 12.5k winch. An AEV Snorkel was additionally added to make sure that the 6.6L Duramax diesel engine is respiratory the cleanest air doable, even below probably the most excessive circumstances off-road.
Underbody safety is important when navigating via technical terrain, so AEV put in the stamped metal entrance skid plate, IFS skid plate and switch case skid plate from the Sierra HD AT4X AEV Edition. For suspension, AEV labored instantly with the GMC engineering group to include a wide range of Sierra HD AT4X elements, similar to management arms, steering knuckles, rear suspension, and Multimatic® DSSV dampers. This factory-tuned mixture supplies 1.5-inch carry over commonplace HD fashions and delivers improved off-road efficiency and flexibility, with out sacrificing consolation or sturdiness.
Thanks to the extra carry peak gained from the AT4X elements and a pair of HighMark fender flares, AEV put in a set of huge, 40” BFGoodrich tires mounted on a set of AEV Salta XD wheels. Rounding out the construct, an 8-foot aluminum tray mattress was put in, together with an AEV vertical tire mount, customized AEV rear bumper, ComeUp 9.5k winch and an ARB on-board air system.
So you get a strong diesel engine with one of many greatest suspension setups on a contemporary truck. The suspension is definitely inventory, and the truck’s peak comes from the 40-inch tires, that are even larger than these worn by the machines that compete on the Mint 400. The fender flares allowed AEV to suit the larger tires, and airing them up or down is simple with the onboard air compressor.
There are twin chucks for the air compressor, one on both aspect of the truck. These are built-in into the aluminum mattress — which isn’t a dump mattress, though the aspect panels swing open. That’s as a result of the Sierra Grande is all about off-roading. It’s even acquired a fabric inside, as a result of vehicles don’t want leather-based seats. This isn’t a luxurious automotive.
Luxe crew cab vehicles being the preferred fashions is only a reality these days. People hardly purchase single cab vehicles anymore. And single cab, lengthy mattress vehicles are roughly extinct. But AEV and GMC have vindicated the only cab with an idea that willl doubtless by no means attain manufacturing, however is unimaginable all the identical.
