GMC x AEV Sierra Grande Concept Truck
American Expeditionary Vehicles and GMC are bringing an uprated GMC Sierra HD AT4X to the 2023 SEMA show. Sierra Grande gets all the goodies that come standard on the Sierra AT4X: Multimatic DSSV dampers, steering knuckles, control arms, and rear suspension. AEV adds a suite of stamped-steel underbody skid plates, a front bumper with brush guard and winch, and 7000-series LED off-road lighting. An AEV snorkel routes clean air to the 6.6-liter Duramax diesel under the hood, and 40-inch tires cover AEV's Salta XD wheels. The truck carries an 8-foot aluminum tray bed, an AEV vertical tire mount, rear winch, and an ARB on-board air compressor. The Sierra Grande concept will be at the 2023 SEMA show beginning October 31st.
