The 2025 GMC Sierra 3500 HD Chassis Cab is a workhorse that delivers uncompromising performance. The Sierra 3500 HD Chassis Cab offers two powerful engine choices. The available 6.6-liter V8 Diesel Turbocharged engine cranks out an impressive 470 horsepower and 975 pound-feet of torque, while the standard 6.6-liter gasoline V8 generates a still-robust 401 horsepower and 464 pound-feet.
Backing up those muscular engines, the Sierra HD Chassis Cab offers a choice of two 10-speed automatic Allison transmissions, engineered to optimize power and efficiency. Paw Paw drivers can also select between rear-wheel drive (RWD) for maximum payload capacity or 4-wheel drive (4WD) for enhanced traction and capability, depending on their work requirements. Two trims are available, SLE and Pro, both generously equipped with standard features like LED lighting, power accessories, and an array of airbags and stability control systems.
Inside, you'll find comfortable seating and a range of available amenities to make long days more productive, from rubberized vinyl floor mats to power-adjustable heated mirrors.
