A vehicle, system and method of controlling a roll of the vehicle is disclosed. The system includes a roll control actuator, a first switch, a second switch and a processor. The first switch is configured to couple the roll control actuator to a first power source. The second switch configured to control an electrical connection between the roll control actuator and ground. The processor is configured to operate the first switch to electrically decouple the roll control actuator from the first power source and operate a second switch to ground to short the ARC motor to ground to control the roll of the vehicle.

A self-contained pneumatic anti-sway assist vehicle body roll control system to supplement existing vehicle suspension by means of sharing load support primary and secondary volumetric gas chamber pressures for soft ride over normal, level road surfaces; then by blocking said secondary gas chambers at load side of vehicle to summarily increase spring rate within its primary load support gas chamber for increased vehicle body suspension support during lateral forces encountered with right and left turns and/or with vehicle body lean when off-camber.

A control system for a suspension height adjustment mechanism of a vehicle. The suspension height adjustment mechanism comprises a front suspension height adjustment mechanism at a front end of the vehicle and a rear suspension height adjustment mechanism at a rear end of the vehicle. The control system is configured to control the suspension height adjustment mechanism in response to user-generated control signals to: increase the height of at least the rear end of the vehicle to a first predetermined vehicle height corresponding to a High tow hitch height; and decrease the height of at least the rear end of the vehicle to a second predetermined vehicle height corresponding to a Low tow hitch height. Both the first and second predetermined vehicle heights are accessible from one or more other vehicle height that is different to the first and second predetermined heights. Decreasing the vehicle height from the High tow hitch height to the Low tow hitch height comprises the control system controlling the suspension height adjustment mechanism such that the height of the front end of the vehicle is decreased less than the height of the rear end of the vehicle.
