EkoStingerEkoStinger is passionate about bringing the trucking industry the very best in tractor trailer aerodynamics. The Stinger System saves fuel, reduces road mist, stabilizes trailers in high cross winds, eliminates snow and ice buildup, and prolongs semi-trailer life. Comprised of a one-piece polyethylene molded stinger and aero mist reducing mud flaps, the system slides with varying tandem positions and provides the optimum alignment under changing driving conditions without interfering with loading and unloading maneuverability.
