Rear-drag fairings

Updated Nov 2, 2010

The TrailerTail rear fairings use an aerodynamic design and ultra-light thermoplastic composite materials to reduce rear drag. The fairings use a collapsible origami architecture for convenience. According to a third-party test, the trailer can offer fuel savings of more than 6 percent, the company says. The fairings come with a 90-day risk-free offer.
