A device for selectively positioning a side wing relative to the side of a motor vehicle it is mounted on and to the adjacent road surface is disclosed. The device includes first and second longitudinal end members pivotally connected to the vehicle side and to a rearward end of the side wing about vertical axes; the front end of the wing is usually connected adjacent the front end of the vehicle. First and second elongate rams that are angularly positioned relative to one another are connected to the first and second end members. The first and second rams operate in parallel relative to each other for selective operation of the side wing from a position adjacent the vehicle side and away from the ground surface to a position in operative engagement with the road surface at an adjustable angle relative to the vehicle side.
