A hydraulic cylinder for a rear eject body for a truck is provided. The body includes a floor and a pair of opposing sidewalls. A tailgate extends between the opposing sidewalls at a rear end of the rear eject body. The tailgate is pivotally supported for movement between an open position and a closed position. An ejector is supported in the rear eject body for movement between a retracted position at a forward end of the body and an extended position at the rear end of the body. The hydraulic cylinder includes a regenerating hydraulic circuit that causes oil coming out of the retract side of the hydraulic circuit to be directed into the extend side of they hydraulic cylinder, which enables the hydraulic cylinder to extend more quickly than would otherwise be possible.
