WARNING CA Proposition 65
The Suspension Conversion Kit will eliminate the original Air Spring Bags and return the vehicle back to factory height. Also included in this kit are four insulators two for the top, and two for the bottom of the Coil Springs. Easy step by step instructions will come with the kit. Suspension Conversion kits are a popular solution for Suspension Air Spring Bag Dry Rot Problems. This Coil Spring Conversion Kit eliminates the Air Suspension without sacrificing comfort. This kit comes with a **Limited Lifetime Warranty** against any manufacturer defects and included with your purchase you will find easy to follow installation instructions.


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.
