WARNING: DRIVING A LOWERED VEHICLE COULD BE DANGEROUS AND COULD CAUSE DAMAGE TO YOUR SUSPENSION

The original intent of the air spring was to provide a very smooth ride.  It was not designed to provide an adjustable ride height.  You can not drive the vehicle at any ride height you select.

All suspension systems are designed to operate at a specific midpoint position, with provisions for suspension travel. The Mustang II suspension is no exception. It has a specific mid-point position which is when the lower control arms are level. The suspension must be in this position to provide full suspension travel and correct geometry action.

In this type of suspension the shock is normally the bottom out device. When the vehicle is lowered the shocks compression and extension limits change and the shocks will bottom out or the ball joints could pinch when it is lowered. The air ride suspension is only designed to lower your vehicle while it is parked. If you attempt to drive a vehicle in the lowered position it could be dangerous and will cause damage to your vehicle. This could result in broken control arms, shocks and ball joints.
