Abstract: A pickup bed ballast assembly for providing added traction while taking up a limited amount of pickup bed space. The pickup bed ballast assembly includes a pair of generally rectangular box shaped main containers and a pair of generally rectangular cover members. Each main container includes a pair of end walls, a first side wall, a second side wall and a bottom wall. Moreover, the main container forms a holding cavity that is used for holding a quantity of sand. The cover members are designed to selectively cover the holding cavities. Each main container is designed to fit over an associated wheel well in a bed of a pickup. In addition, each main container is coupled to the bed of a pickup thereby holding the main container in a static position.
