Suncore Industries was established in 2000 and have been a member of the Automotive Parts Rebuilders Association (APRA) ever since. Our mission began with rebuilding air suspension components and moved quickly into offering better solutions with conventional suspension conversion kits to give our customers the longevity they can rely on.

The most common reason for an air strut failure is due to dry rotting of the air bag. This is something that happens over time, the air bag starts to deteriorate and causes leaks, when this happens the air bag can no longer hold air pressure. A leaking air bag can cause the strut it fits over to fail as well. The second factor of an air strut failure is the strut itself. The strut is pressurized with fluid, and if the strut begins to fail it will no longer have the same pressure to hold the vehicle. If this system begins to fail one visible sign will be that your vehicle will be lower than factory height. If Air Struts are not replaced on time, it will cause an Air Suspension Compressor Failure.

Rear Air Suspension to Coil Springs & Shocks Conversion kit - Town Car - Crown Victoria & Grand Marquis

Hello, I am thinking about converting to Coil Spring for my 2003 Town Car Executive Sedan. After the Installation, would I have the Same Height in rear ? Would I have Suspension Light on at the Cluster ? How is ride compared to factory Air Spring ? Lastly, Do I need any special tool to installation as I am trying to install at home with Floor Jack and Jack Stands ? Thanks,

Customer Service

Daniel, Glad to help answer your questions! Yes, your vehicle will maintain the same factory ride height and will keep a quality ride. Conversion will be more stiff, but this offers better handling and cornering. Our instructions offer a way to bypass your dash light from coming on as long as your other suspension components are properly functioning. You will need the vehicle jacked up all the way around for this installation to go smoothly. Our instructions also include diagrams to help you out! If you have further question please let us know, we are happy to assist!
