FEATURE HIGHLIGHTS

BUILT STRONG TO TOW STRONG

Sierra HD Denali was built strong so you can tow strong — with its large drive shaft and rear axle, the power of the available Allison®† 10-speed automatic transmission, the first in a heavy-duty truck in its class, and available 6.6L Duramax® Turbo-Diesel V8 engine is maximized so you can tow with command and control.

TECHNOLOGY TO TOW SMART

Available technologies, such as up to 15 available camera views and the 15" diagonal Head-Up Display let Denali drivers tow smarter, not harder.

PURPOSE-BUILT EXTERIOR

Denali’s eye-catching exterior features many exclusives that help give the vehicle its signature look: Signature Denali grille with chrome inserts, 6" chrome Assist Steps, chrome Vertical Front Recovery Hooks, standard 20" Multi-Dimensional Polished Aluminum Wheels and more.

EXCLUSIVE PREMIUM INTERIOR

The spacious, comfortable cabin features innovative driver-centric technologies, premium materials, such as authentic open-pore ash wood, brushed aluminum trim, chrome accents, and a ton of Denali exclusives: premium interior colours, Forge perforated leather seating surfaces with front heated and ventilated bucket seats and more.

HIGH-STRENGTH CHASSIS AND SUSPENSION

HIGH-STRENGTH CHASSIS AND SUSPENSION

The strong chassis, suspension and wheelbase (standard/long: 158.94"/172") are built upon a fully boxed, ladder-type frame built from high-strength steel using front hydroformed rails with clamshell design. The optimized frame and body structure works in conjunction with large driveline components that feature high-strength axles featuring large ring gears (11.5" on 2500, 12" on 3500) to bring immediate torque to ground for towing and off-roading.
