Flow Below Aft Adapter Support
Freightliner

Flow below aft adapter support is a structural element that anchors the lower transition section and stabilizes the flow path of air around the vehicle rear. The painted black finish protects the component on exposed surfaces and helps conceal minor scuffs that occur during maintenance. This piece contributes to aero efficiency by maintaining a consistent surface plane and reducing abrupt geometric changes that could disrupt smooth airflow. By strengthening adjacent panels and reducing vibration at the joint, it helps prolong the life of surrounding components and reduces noise transmission. A reliable support like this reduces the need for frequent adjustments, supporting predictable performance through varying loads and road conditions. Source One Parts Center.
