An apparatus includes a dump box having an open end and a tailgate supported on the dump box for movement between a closed position, wherein the tailgate closes the open rear end of the dump box, and an opened position, wherein the tailgate is spaced away from the open end of the dump box. A cylinder assembly extends between the dump box and the tailgate. The cylinder assembly includes a cylinder and a piston that is able to move relative to the cylinder for selectively moving the tailgate between the closed and opened positions. The cylinder assembly has a cross-sectional shape that is non-circular.
