A vehicle active tilt control system torsionally adjusts front and rear stabilizer bars during vehicle maneuvers. A source of pressurized fluid is provided in communication with a directional control valve. Front and rear actuators each have opposing fluid chambers for receiving fluid from the directional control valve to cause actuator movement for adjusting the front and rear stabilizer bars. Each opposing fluid chamber of the rear actuator includes an inlet with a calibrated orifice therein for restricting flow therethrough to slow movement of the rear actuator for optimal timing of rear actuator movement with respect to front actuator movement. Preferably, the actuator includes a moveable piston with first and second plugs extending therefrom for cooperation within first and second outlets, respectively, in opposing fluid chambers of the actuator to at least partially restrict the fluid flow through the outlets as the pistons approach the fully stroked positions, thereby cushioning piston movement near the end stops.
