Abstract: A device for selectively adjusting and maintaining the angular position of a truck's tailgate relative to the truck's bed. The device generally includes an elongated threaded rod, a clamp attached to one end of the rod and adapted for engagement with a pin on the truck's bed, and a clevis attached to the opposite end of the rod and adapted for engagement with the tailgate's latching mechanism. A roller interconnected to the clevis permits smooth, pivotal movement of the tailgate between its modified (partially) open position and its fully closed position, and also permits attachment to various truck models.
