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.

This kit is a great low tech upgrade for older vehicles and is way cheaper then replacing air ride shocks and compressor. It also comes with the dashboard signal bypass kit as well. My 2005 Escalade ESV and 2003 EXT both ride great again for a minimal cost.

Will this conversion kit increase your payload capacity?

Customer Service

Hi William, This kit offers the upgraded shocks to improve rebound when towing or reaching load limit. it is not designed to exceed factory capacity.

Will this make my 03 not squat anymore and bring it back up to stock ride height..

Customer Service

Thank you for reaching out, yes this kit will match & restore stock height.
