The Tractor AeroKit with Flex Fairing from FlowBelow features flexible wheel fairings that can return to their original shape after impact, a redesigned rear fairing, and lighter dynamic center fairing. All are built from aluminum to decrease weight and increase corrosion resistance. It also inclues telescoping center mounting bars to make it easier to reach the fifth wheel, remove the fairings, and install chains. More easily transferable from one truck to another, the flexible fairings and lowered rear hanger option lets fleets that pull pups or intermodal containers use this aero kit. Comes with a five-year, 500,000-mile warranty.
