Designed for the best aerodynamic performance, we used Computational Fluid Dynamics to test, refine and validate. Peterbilt's flexible Aero Packages provide the right combination of fairings, skirts and closeouts to exceed application-specific aerodynamic requirements. Available in a day cab, or with detachable sleeper, that adds versatility and longevity of a second life for highest resale value.
