An apparatus is provided for raising and lowering a vehicle that is supported by a wheel suspended from a frame of the vehicle by a suspension component. The apparatus includes a linear actuator that is vertically oriented to move the wheel of the vehicle relative to the frame of the vehicle. A compression device is arranged to compress the suspension component of the vehicle in response to movement of the wheel by the linear actuator.

A vehicle lowering system having a cargo surface with an adjacent pivoting arm is connected to a vehicle at a pivot point. The pivoting arm moves between a raised and a lowered position by an actuator that is affixed to a frame and the pivoting arm. The frame has an upper portion and a lower portion that provides structure for the portion of the frame that is beyond the pivot point and actuator. The pivot arm has a spindle that holds and allows a wheel to rotate. The spindle has an axis that is always located above the cargo surface. The actuator is movable between an extended position and a retracted position. When the actuator moves between the extended and retracted position, the pivoting arm moves the vehicle between a raised and a lowered position.

A vehicle lowering system is provided having a movable arm that is connected to a vehicle through an upper link and a lower link. The upper and lower links pivot with respect to the vehicle on pivot points on one end and pivot with respect to the arm on pivot points at the opposite end. The spacing of the pivot points and the length of the upper and lower arm create an instant center, about which the movable arm pivots. An actuator is connected to the vehicle on one end and the movable part of the suspension on the opposite end. The actuator is movable between an extended and a retracted position. When the actuator moves between the extended and retracted position, the movable arm moves the vehicle between a raised and a lowered position.
