The ALP3 Stance Guard is an extra safety precaution for your 3P or 3H equipped vehicle. This safety device plugs in between the controller and the main harness and serves two purposes. It will emit an audible alarm when the vehicle is below or above a user-specified driving pressure to remind the user that the vehicle is not at a safe height to drive. It will also prevent the user from making intentional or unintentional adjustments while the vehicle is in motion. A lock will appear on the screen while in motion and any attempt to change the height will result in a "Stance Guard Lockout" fault appearing and will put the system in manual mode until you can bring the car to a stop and adjust it.
This product is especially useful for the Australian or certain European markets where laws surrounding adjustable suspension are much more strict.
