The FlowBelow Trailer AeroSlider underwent rigorous rolling-floor wind tunnel testing at ARC (Aero Research Consultants) in Indianapolis, Indiana, as part of a comprehensive development and validation process.

CFD Tested
CFD Tested

Wind tunnel testing was conducted alongside computational fluid dynamics (CFD) modeling to optimize the AeroSlider’s design before proceeding to on-road validation.

The outcome is a portfolio of aerodynamic devices that deliver proven, measurable fuel economy improvements (ranging from 0.7% to over 2%) based on rigorous testing rather than theoretical assumptions.

BENEFITS

  • ~75% less surface area with higher drag reduction. Slider travel not restricted (no holes plugged).

  • Performs with or without flow through mudflaps. Flow-thru flaps provide additional drag reduction with similar performance for different flow-through flaps.

FREQUENTLY ASKED QUESTIONS

How durable is the Trailer AeroSlider System?
The Trailer AeroSlider System was designed alongside major fleet partners and is made to standards specified by large fleet mechanics and drivers. The rear fairing, mudflaps and wheel covers are made from 100% rust proof polyethylene and are engineered to maintain maximum durability even in known extreme weather conditions and temperatures. 

Does the Trailer AeroSlider System work with Trailer Skirts or Tails?
The Trailer AeroSlider System improves fuel efficiency with or without additional trailer aerodynamic devices such as side skirts and boat tails. Because the Trailer AeroSlider System addresses the drag intensive area around the wheels of the trailer, it is effective no matter what type of trailer you pull. 

Is the Trailer AeroSlider System compatible with my existing wheels and tires?
The FlowBelow Trailer AeroSlider System works with most wheel and tire configurations, including super singles.  

Can I easily access my tires when the wheel covers are installed?
The wheel covers utilize FlowBelow’s patented quick release system to provide drivers and maintenance staff with instant, tool-free access to the wheels. Just push and turn the wheel cover to remove it in seconds. To re-install, simply place the wheel cover over the wheel and turn until the quick release clicks, letting you know that is is securely fastened. 

Can I use tire chains with the Trailer AeroSlider System?
Absolutely. The wheel covers only interact with the wheel hub and provide plenty of access to install and remove your tire chains in winter conditions.

What color options are available?
The fairings are available in both black and white while the wheel covers are available in black, white or chrome.
