The simple science
As air moves over a vehicle, it wants to separate at the vehicle edge. Airtabs guide that separation into a more stable pattern, which reduces the vacuum effect that pulls on the trailer and wastes fuel.
How It Works
Why Airtabs help trailers, campers, and motorhomes move cleaner through the air.
Airtabs are small aerodynamic fins mounted on the vehicle edge. They change how air separates from the vehicle, reducing the low-pressure pocket that forms behind the cab and trailer. That calmer airflow means less drag, less turbulence, and better fuel economy.
What you feel
Drivers often notice a more stable ride, less trailer sway, and cleaner wind flow along the back of the rig. The result is smoother performance and better efficiency at highway speed.
Key points at a glance
- • Airtabs help break up the turbulent wake behind the cab.
- • They reduce the low-pressure drag pocket that slows the rig.
- • Better airflow can improve fuel efficiency and stability.
- • They are simple to install and work on many trailer, camper, and motorhome vehicle rooflines.
- • Plan for 3 Airtabs per linear foot of vehicle edge length.
