The apparatus comprises an attachment member for securing the apparatus to a gooseneck trailer. A rectangular housing is secured to the attachment member, and has a front wall, a back wall, and at least one side wall. A cavity is formed by these walls. A ball receiver is pivotably secured internal to the housing and has an opening for the passage of a spring rod. A shock absorbing mechanism is provided, which is secured generally perpendicularly to the housing, and includes at least one spring element. When the ball receiving member pivots towards the front wall, it pushes a bushing disposed on the central rod into the spring element, causing the spring element to compress. When the ball receiving member pivots towards the back wall, it pulls a back plate that causes the spring element to compress.
