Lightweight mud flap

Available in 24-in. square, 24- x 30-in. or 24- x 36-in. sizes, the Air Pass Mud Flap offers weight reduction potential of 60 percent or more when compared to conventional rubber flaps, which can create drag when winds hit a truck or trailer. Using computational fluid dynamics testing, company engineers measured a 0.4 percent fuel savings on vehicles fitted with Air Pass Flaps versus a conventional flap-bearing bearing control. The former are made with an engineered, high impact Nylon compound that can withstand exposure down to -70°C, and can be customized with logos or other operator graphics.
