Our rugged 2021 GMC Sierra 3500 SLT Crew Cab 4X4 is impressively well equipped for working harder with Diesel power and a bold White Frost Tricoat finish! Motivated by a TurboCharged 6.6 Litre DuraMax Diesel V8 serving up 445hp and 910lb-ft of torque paired to a 10 Speed Allision Automatic transmission for awesome strength.
