A wedge system for stabilizing a liftgate of a vehicle relative to vehicle structure of the vehicle includes a first member for mounting on one of the liftgate and the vehicle structure. The wedge system also includes a second member for mounting on the other of the liftgate and the vehicle structure. The wedge system further includes a third member disposed between the first member and the second member and being movable and adjustable relative thereto to accommodate a gap between the liftgate and the vehicle structure and to stabilize the liftgate by providing a load path from the liftgate to the vehicle structure when the liftgate is in a closed position.
