Sierra Grande Concept – A Presence You Can’t Ignore

In the world of heavy-duty trucks, presence is everything. The AEV Sierra Grande Concept is no shrinking violet. It’s a leviathan that commands attention, standing tall and wide with a menacing aura. Inspired by the Sierra HD AT4X, this truck showcases its abilities in a compact, regular cab layout—giving it a muscular, bulldog-like stance.

Sierra Grande Concept – Purpose-Built for the Adventurer

If your idea of a weekend getaway involves a camper in the back or towing a heavy trailer deep into the woods, look no further. AEV has pulled all stops to make this not just an off-roader but a top-tier overlander. The aluminum tray bed—installed in an 8-foot configuration—provides maximum versatility for both storage and auxiliary setups.

Sierra Grande Concept – Guarded but Never Blind

Ever thought you’d have to compromise between fortifying your front-end and the essential visibility offered by a front camera system? Think again! This beast comes with a prototype brush guard that integrates flawlessly with the front camera, ensuring that while your truck stays protected, your vision remains unobstructed.

Twin Winches: Because Getting Stuck is So Last Decade

The Sierra Grande is not just about looking good; it’s about getting you out of tight spots—literally. With dual winches—a GM Performance/ComeUp 12.5k at the front and a ComeUp 9.5k at the rear—this rig doubles as your very own recovery vehicle. Forget about ever getting stuck again; this truck has more pulling power than a tractor beam in a sci-fi flick.

Sierra Grande Concept – Specs that Leave You Breathless

Let’s dig into the meat of it:

  • Engine: A 6.6L Duramax diesel that breathes through an AEV Snorkel for superior air quality in the most trying off-road conditions.
  • Suspension: Factory-tuned AT4X components combined with AEV modifications result in a 1.5-inch lift over standard HD models. You’re looking at steering knuckles, control arms, rear suspension, and Multimatic® DSSV dampers that redefine off-road performance without compromising comfort or durability.
  • Wheels and Tires: If you thought your tires were large, wait till you get a load of these—40-inch monsters sitting pretty on AEV Salta XD wheels.
  • Skid Plates: Your underbody is shielded by stamped steel skid plates at the front, IFS, and transfer case, because AEV understands that ‘vulnerability’ is not in your vocabulary.
  • On-Board Air System: For the self-sufficient traveler, this is your built-in pit crew for tire maintenance.
  • Custom Rear Bumper and Lights: Because it’s the little things that make a big difference- AEV Included (4) 7000 Series off-road lights and custom rear bumper to match the tray bed.
