Abstract: An adjustable vehicle step that attaches to the vehicle's frame or body via a downward facing c-channel that extends longitudinally along the lower edge of the side of the vehicle. One or more step assemblies can be attached to the c-channel so that the step assemblies extend outward and downward from under the vehicle. The step assemblies are attachable along the length of the c-channel, making the step assemblies adjustable longitudinally relative to the vehicle so that they can be positioned below the doors of the vehicle. The supporting c-channel is hidden from view by a decorative side bar that attaches to the exposed side of the c-channel making the step assemblies appear to be supported by the decorative side bar. The step assemblies used with the step can be made of various lengths and heights.
