Aerodynamic Splash Guards Built to Improve Safety and Fuel Economy

Eco Flaps are SmartWay-verified aerodynamic splash guards designed to reduce road spray, improve fuel efficiency, and withstand the demands of daily fleet operation.

Built for fleets. Proven through third-party testing. Designed for real-world durability.

More Than a Mud Flap

Traditional mud flaps create drag, reduce visibility in wet conditions, and often fail under tough road conditions. Eco Flaps were designed to solve those problems.
 
Eco Flaps use a patented, ventilated design that allows air and water to move through the flap surface instead of building resistance behind it. The result is improved aerodynamic performance, reduced road spray, and increased durability compared to conventional mud flaps.
 
Manufactured from high-impact nylon polymer, Eco Flaps are engineered for fleets looking to improve performance without adding complexity to installation or maintenance.

Backed by a no-questions-asked 2-year warranty

Traditional Mud Flaps

  • Blocks airflow
  • Builds drag behind the flap
  • Can increase airborne spray

Eco Flaps

  • Vented design
  • Allows air and water to pass through
  • Helps reduce drag and spray

Why Fleets Choose Eco Flaps?

Fuel Savings

 Wing-shaped channels move air through the flap surface to reduce drag and improve aerodynamic performance.
 
Third-party testing has demonstrated measurable fuel savings across multiple fleet applications, helping Eco Flaps pay for themselves over time through reduced fuel consumption.

Third-party-tested

Improved Safety

Eco Flaps help direct water toward the pavement instead of into the air, reducing the heavy spray clouds that can limit driver visibility in wet weather.

The result is improved visibility for both truck drivers and surrounding motorists.

Built for Durability

Eco Flaps are manufactured from impact-resistant nylon polymer designed to perform in demanding road and weather conditions.

They have been tested to withstand extreme temperatures without cracking, breaking, or melting.

Backed by a no-questions-asked 2-year warranty.

Fleet-Ready Installation

Eco Flaps install using existing mud flap mounting locations without requiring additional hardware or equipment.

Available in multiple sizes and configurations, Eco Flaps are designed to fit a wide range of tractor and trailer applications.

65 MPH Road-Spray Comparison

Traditional mud flaps can create dense road spray that reduces visibility for nearby drivers in wet conditions.

Eco Flaps are designed to direct water downward toward the pavement, helping reduce airborne spray and improve roadway visibility.
