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.

Air Suspension Coil Spring Conversion Kit - Lexus LS430 RWD

Does your conversion kit work for the 2005 LS 430 with Ultra Luxury Package? Thanks

Customer Service

Hello, yes our 69T-31-4 will be compatible. Be sure to keep your actuators plugged in to avoid a dash light!

How close do these come to the Lexus Factory shock and coil spring tension, of an LS430 with normal Lexus (non Air suspension) strut coil spring suspension which comes standard with the Non Luxuary edition?

Customer Service

Thank you for reaching out. These are built to the Factory specs, of the Struts from the Models without Factory the Air Suspension, so it will ride just as the Models with the Conventional Suspension from factory. PLEASE NOTE THESE WILL ONLY FIT RWD MODELS. Regards, Marcelo
