QUIETLY GOES ABOUT ITS BUSINESS

The Sierra Denali HD cabin combines triple door seals, inlaid doors, specialized powertrain mounts and

other engineering achievements to create an exceptionally quiet environment. It’s the solitude, comfort

and craftsmanship you never expected in a heavy-duty pickup. Denali is also loaded with premium

materials, along with French seam stitching, supportive heated and ventilated leather-appointed front

bucket seats and generous storage. A hand-stitched heated leather-wrapped steering wheel and

soft-touch instrument panel with burnished aluminum trim distinguish the premium-duty Sierra Denali

HD from all others.

SLT

BOLDLY GOES WHERE YOU WANT

The first thing you notice about the Sierra SLT is its bold, precisely sculpted design that looks smart and works efficiently.

The large three-dimensional grille is designed to capture air to help cool the engine, while the remaining air flows

smoothly around the truck. And since it’s a Sierra HD, it produces robust payload and trailering capabilities.
