Performance
Under the hood, the Sierra 3500 HD comes standard with a brawny 6.6-liter V8 gas engine churning out 401 horsepower and 464 lb-ft of torque. Paired with a robust Allison 10-speed automatic transmission, this powertrain provides ample muscle for confidently hauling heavy trailers and payloads around the Allegan area. For even greater pulling power, the available 6.6-liter Turbo Diesel V8 unleashes an incredible 470 horsepower and 975 lb-ft of torque on Denali Ultimate models.

Cab Configurations and Trims
With three cab styles and up to six trim levels, the Sierra 3500 HD can be configured to suit a wide range of needs and preferences in the Battle Creek area. The Regular Cab provides a classic two-door design with a full-size bed, while the Double Cab and Crew Cab offer extended or full-size rear doors and a spacious backseat. Depending on the configuration, bed lengths range from 6 feet 9 inches up to 8 feet 2 inches.
Climbing the trim ladder, the Sierra 3500 HD offers increasing levels of refinement, technology, and amenities. Even the base Pro model comes well-equipped with convenient features like a corner step rear bumper and cargo bed LED lighting. SLE and SLT trims introduce progressively more comfort and technology for a premium ownership experience around Kalamazoo. 4WD-equipped models are also available for enhanced traction and stability in tough conditions.
Rugged AT4 and Refined Denali Models
For traversing rough terrain and trails outside Paw Paw, the Sierra 3500 HD AT4 comes prepared with standard 4WD, off-road suspension, skid plates, and an Eaton locking rear differential. Inside, the AT4 treats occupants to upscale amenities like a Bose premium audio system, heated front seats, and wireless charging.
At the pinnacle of the lineup, Sierra 3500 HD Denali and Denali Ultimate models blend professional-grade capabilities with first-class accommodations. Premium leather seating, open-pore wood trim, and intuitive tech features like a 15-inch diagonal Head-Up Display create a truly luxurious cabin experience. With the diesel powertrain, Denali Ultimate is the most capable and sophisticated Sierra HD ever offered.
