The Michelin Energy Guard aerodynamic trailer solution kit is designed to improve fuel economy on 53' dry-van truck load, refrigerated truck load and other long-haul and super-regional applications. The kit is made up of five components: a fully flexible trailer skirt, a reinforcing bracket and slider, aerodynamic mud flaps, a wake reducer and drag-reducing trailer end fairings. The trailer end fairings and wake reducer are automatically functioning, always activated requiring no driver actions. All five pieces of the kit add a total 280 lbs to the trailer. Components are designed to be used as a full package for proven fuel savings.
