1. A vehicle active tilt control system for torsionally adjusting front and rear stabilizer bars during vehicle maneuvers, the system comprising:

  • a source of pressurized fluid;

    a directional control valve receiving pressurized fluid from said source; and

    front and rear actuators each having opposing fluid chambers to receive fluid from the directional control valve to cause actuator movement for adjusting the front and rear stabilizer bars;

    wherein each opposing fluid chamber of said front and rear actuator includes an inlet, and the in lets of the rear actuators having a calibrated orifice therein which renders the rear actuator inlets smaller than the front actuator inlets to restrict flow to the rear actuator relative to the front actuator to slow movement of the rear actuator to synchronize rear actuator movement with respect to front actuator movement during vehicle maneuvers.
