This clean title 2021 GMC Sierra 1500 AT4 Crew Cab arrives with GM's 3.0L Duramax Turbo-Diesel inline-6, a clean-sheet engine that debuted for the 2020 model year and earned a Wards 10 Best Engines award for its smoothness and pulling power. Paired with a 10-speed automatic and 4WD, this diesel makes 277 horsepower and 460 lb-ft of torque, with peak torque arriving at a low 1,500 rpm for strong, confident power whenever you need it.

The AT4 trim brings GMC's off-road-focused equipment on top of that, including Hill Descent Control, Hill Start Assist Control, and the Towing Package for serious hauling capability. Inside, heated and ventilated leather seats, dual power seats, and a tilt and telescoping wheel keep every drive comfortable, while the Premium GMC Infotainment system, navigation, Bluetooth wireless, and SiriusXM Satellite keep you connected. A power sunroof and LED headlamps round out the standout features.

Safety is well covered too, with StabiliTrak, traction control, a backup camera, Side Blind Zone Alert, and a full suite of side and head curtain airbags working together. Keyless entry and keyless start add everyday convenience, and a spray-in bed liner protects against the wear that comes with real work.

Clean title, GM's award-winning diesel inline-6, and genuine AT4 off-road capability make this Sierra a smart, capable choice that holds its value well above the gas-only competition.
