Engineered for todays tow vehicles. The AeroShield's aerodynamic design reduces wind resistance and practically eliminates turbulent winds trapped between the tow vehicle and the fifth wheel or trailer, ensuring smoother handling and improved performance. The AeroShield can be adjusted to virtually any angle allowing maximum aerodynamic efficiency and easily folds down when not in use. Ships completely assembled (includes mounting hooks No. 2, No.6, No.8 and No.9) ready for installation.
