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.
Converting your vehicle from air suspension to a coil spring kit is an easy process that does not require any modifications to the vehicle. Taking the place of the air spring bags will be the coil springs specifically designed to fit the vehicles suspension. For good ride quality gas shocks should be replace as well. Every vehicle can be different, but most gas shocks last up to 50,000 miles and can affect the suspension. In the front of the vehicle the air shocks will be replaced by coil over shocks. Keep in mind that if you do convert to a coil conversion kit, the old air system will still need to be in place for electronic purposes.
