A lift device includes a chassis, an implement assembly including an implement actuator, and a lift assembly coupling the implement assembly to the chassis and configured to raise the implement assembly relative to the chassis. The lift device further includes at least one of a gyroscope assembly, a hydraulic stabilization system, or a first boom portion and a second boom portion. Rotation of a flywheel causes the gyroscope assembly to apply a force to the implement assembly to oppose movement of the implement assembly. Responsive to movement of the implement assembly when a valve is in a closed position, fluid flowing between the implement actuator and a fluid source is directed through an orifice via a second supply line, thereby restricting the flow of fluid and dampening the movement of the implement assembly.
