Airtabs™ are patented, unique wishbone shaped vortex generators designed to increase vehicle aerodynamic performance and fuel economy by reducing aerodynamic pressure drag at two key locations; the tractor-trailer gap and the rear facing surface (the base area) of any commercial or private square backed vehicle or trailer that routinely attains highway speeds. Drag reduction and fuel economy benefits from Airtab® application is not limited to commercial trucking operations. Airtabs™ enhance aerodynamic performance equally well on cube vans, straight trucks, expeditors, SUVs, RVs, buses, horse, toy and utility trailers, faired “bob tail” tractors, flat beds and tankers. The results may vary somewhat with vehicle type but the aerodynamic theory and principles are the same for all.

Each Airtab® creates two tight swirls of air or vortices that combine to reduce the suction and drag at the rear of vehicles traveling at speeds above approximately 35 mph or 55kmh. Airtabs™ are also effective at the rear roof lines of automobiles that have a rear window slope of greater than 30 degrees.

Airtabs™ offer several safety benefits as well. They improve vehicle stability by altering the airflow at the vehicle’s rear. The large random eddies at the rear surface are changed to an array of small vigorous “stream wise” vortices. The majority of users comment immediately on the improved vehicle handling performance, especially in gusty cross wind conditions or when passing (or being passed by) other vehicles. This increases driver safety margins by reducing wandering and sudden adjacent lane incursions. Mirror visibility in rain or snow is also improved as the Airtabs™ help suppress precipitation and spray patterns. Safety is improved through better mirror visibility yielding safer lane changes as well as improving the visibility conditions for other road users. By reducing the suction and aerodynamic drag at the rear of vehicles, the tendency to accumulate snow and road grime at this location is reduced. This helps to improve corporate image and reduce cleaning time and expense. It also enhances safety by keeping conspicuity tape, tail and brake lights cleaner and helps the bottom line by reducing snow and weight build up in winter.


Measure the sides and the roof of the Vehicle at the back. They are placed 3 per linear foot (4” inches on center). The Airtabs are installed on both sides and the roof at the trailing edge of the vehicle.

Airtabs™ are mounted 3 per linear foot, or every 4 inches on center. Take the number of feet to be covered and multiply by 3 to give the number of Airtabs™ required. For example if the total distance is 24 feet multiply 24 feet by 3 which equals 72 Airtabs™. Airtabs™ must be installed when the vehicle skin and air temperature is above 40°F (5°C). Attempting to install Airtabs™ when colder will yield unsatisfactory results.

Each Airtab® measures 4.76 inches in length by 3.25 inches in width and will stick out from the vehicle 1 inch.

If you operate a standard tractor or trailer unit:

You need our Tractor or Trailer Kit in either white or black. Each kit contains 80 Airtabs™, enough for one tractor or one trailer. The Airtabs are installed on both sides and the roof at the trailing edge of the vehicle.

Vehicle Applications

Please visit to view vehicle applications and read customer comments.

If you operate an RV or similar large vehicle or other size vehicle:

Measure the sides and top perimeter of the trailing edge of your vehicle. You will need 3 Airtabs™ per lineal foot (mounted no closer than 4″ centers — see install instructions). Purchase either white or black Airtabs™ individually in whatever quantity you need.

We recommend that you buy one or more extra Airtabs™, in case your measurements were slightly off, or you drop one during installation. If you drop an Airtab® after removing the lining and the adhesive gets dirty, you will probably find that Airtab® will no longer adhere to the surface of your vehicle.

Need to equip more than 500 units?

If you need more than 40,000 Airtabs (enough for 500 tractors or trailers), please call Airtab, LLC at 262-394-5752 for fleet pricing.


The Airtab® are priced $2.75 US dollars each for the black or white Airtab® and shipping and handling plus the appropriate sales tax when ordering in Wisconsin or Canada. Credit cards accepted are Visa, Discover and Master Card. All prices are in United States Dollars. Prices are subject to change without notice.

The Airtab may be painted in accordance with the specification of the paint you have chosen. Some paints such as “Krylon Fusion for Plastic” from Sherwin Williams is made specifically for plastic.
