Abstract
A vehicle suspension includes a dock height holding device. First and second jounce bumper portions preferably each include a surface configuration that faces generally toward the oppositely facing jounce bumper portion. By moving at least one of the jounce bumper portions between first and second alignment positions, the clearance between suspension components is controlled in a manner that controls the height of a truck bed or trailer deck. In one example, each jounce bumper portion includes four projections and four spaced recesses. In the first alignment position the projections on one jounce bumper portion are received within the recesses on the oppositely facing portion during normal driving conditions. In the second alignment position, the projections of the jounce bumper portions engage each other and maintain a larger clearance between the suspension components to ensure an appropriate deck height when the vehicle is parked for loading or unloading.
