A rocker board assembly for a motor vehicle includes a housing adapted to be attached to the motor vehicle. An arm is slidable relative to the housing. A pivot housing is pivotal relative to the arm. A step is fixedly secured to the pivot housing. The rocker board assembly also includes a tilt link extending between the housing and the pivot housing for urging pivotal movement of the pivot housing as the arm slides relative to the housing to move the step between a stowed position and a deployed position.
