Functions of this air suspension system: the two air spring bags, located at the rear of the vehicle, are inflated with air when the system recognizes a change. The system works as a unit to maintain ride height as the vehicle is in motion. A height sensor sends a message to the control module that the height of the vehicle is incorrect. Control module will power the air compressor on, in order to fill the air spring bags. Solenoids located at the top of the air bags allow the air to flow in and out of the bags as needed. The same will apply to the air shocks at the front of the vehicle, although there are no solenoids, the system acknowledges the change.
Also located at the rear are gas shocks, these pressurized gas shocks help the vehicles suspension ride. Good for at least 50,000 miles these gas shocks should be changed to ensure good ride quality.
