Product Description

The ICON 56110 Rear Coil Spring Conversion Kit allows owners of 2003-2009 Lexus GX470 and 2010-2024 Lexus GX460 to replace their factory rear air suspension with a more reliable coil spring setup.

It is a direct-fit solution for GX models equipped with factory rear air suspension and is compatible with KDSS. Whether you're preparing for overlanding, towing, or just removing a failing air system, this kit delivers a clean and dependable upgrade.
