Abstract: A high clearance converter is used for converting a road vehicle, e.g. a pickup truck, to a high clearance vehicle, for example for agricultural use. The converter has front and rear frame components, each with two upright and ground wheels mounted on each of the legs. The front wheel hubs are mounted on the front frame component and the rear axle is mounted on the rear frame component. The front and rear frame components are coupled for relative rolling movement with respect to one another, allowing the frame to flex when travelling over uneven ground.
