DUAL ACTION SYSTEM The suspension system incorporates a rear load leveling system that maintains the vehicle at the proper ride height under varying conditions of vehicle load, and an optional road calibrated suspension ride control system that varies the damping of the shock absorbers between soft and firm. The rear load leveling system uses air springs to support the vehicle weight. The quantity of air in the rear air spring is controlled by the vehicle dynamic module (VDM) to maintain a predetermined vehicle ride height. Each air spring has an air spring solenoid to control air flow into and out of each air spring. The optional ride control system uses four shocks with electronically controlled actuators. The shock actuators are internally mounted on the lower bodies of the front spring and shock assemblies and the rear shocks. The action of the shock actuators is controlled by the VDM. The VDM sends a signal to an appropriate shock actuator which switches to either soft or firm damping. Normally the shock actuator setting is in a soft, luxury car mode. This is done by causing an electric current flow through the actuator, which induces electromagnetic force that moves the shock actuator from a firm to a soft position. When driving situations require, the setting is switched to a firm, high performance control mode. This is done by removing power to the actuator, allowing the shock actuator to return to the firm mode.
