Abstract: A flip top locking topper for a pickup truck having a forward wall and a shell. A hinge support is rigidly attached to a forward end of the pickup box along with the forward wall. The shell, attached to the hinge support by one or more hinges, pivots to open and closed positions. A lift mechanism, such as a hydraulic cylinder, linear actuator, or mechanical screw operates to open and close the shell. One end of the lift mechanism can be attached to a lower position on the hinge support. The other end is attached to an inside top surface of the shell. One or more lock blocks are positioned on a lower edge of the sidewalls of the shell. As the shell is lowered, the lock blocks engage and enter stake bed opening on the truck bed sidewalls. From the closed position, the lift mechanism first lifts a forward edge from the forward wall, the pushed the shell rearward to disengage or unlock the lock blocks, and then the shell is pivoted upwards.
