Whereas the Sierra HD AT4X AEV Edition gets 35-inch tires, the concept rides on comically large 40-inch BF Goodrich tires wrapped around AEV Salta XD wheels. AEV HighMark fender flares surround those tires to make sure mud doesn’t get flung all over the custom green paint. Rather than a traditional truck bed, the Sierra Grande features an eight-foot aluminum tray bed with an AEV vertical tire mount, custom AEV rear bumper, and ARB on-board air system.
Few details were provided about the interior, but judging from the photos, the dash looks similar to a stock Sierra HD, which was updated for the 2024 model year. But unlike the production AT4X, this one comes as a regular cab with cloth seats. The Sierra Grande will be on display at SEMA from October 31st through November 3rd.
