Shop the Individual Sierra HD

Two used Sierra HD diesels can differ substantially even when both carry the Duramax name. Model year, maintenance history, previous use, drivetrain, cab and bed configuration, rear-wheel setup, equipment, condition, and how the truck will be used all matter. Evaluate the complete truck rather than reducing the decision to engine badge or trim level.
