The Flip-Over Ball is locked in the one-piece ball socket with a spring loaded stainless steel pin.How It Works:The Flip-Over Ball is locked in the one-piece ball socket with a spring loaded stainless steel pin. To invert the ball, just reach into the driver side rear wheel well and rotate the actuating rod 90 degrees. This cams the retaining pin to the open position. Invert the ball and rotate the actuating rod back to its original locked position. That’s all there is to it!
