An improved connection between articulated bodies for agile vehicles is disclosed. It features independent bodies which are connected to each other with concentric sleeves serving as the pivot to allow the bodies to rotate in a plane parallel to the direction of forward movement. The concentric bushings are preferably made of graphite/epoxy and secured to the chassis body sidewalls. Each of the body segments remains uninterrupted by the bushings which are principally disposed between the facing interior sides of the two bodies. The bearing assembly, which is preferably graphite/epoxy, is self-lubricating as it wears over time. Lateral movement is easily controlled, and relative rotation is also controlled by a collar which serves a dual function to control lateral movement of the bodies as well as relative rotation.
