Product Details

The Monroe Air Spring to Coil Spring Conversion Kit line is intended for vehicles originally equipped with air suspension that need a conventional suspension conversion. For the listed Lexus GX470 and Toyota 4Runner rear applications, Monroe 90022C provides the core components needed to replace the factory air spring setup with coil spring-based suspension parts while retaining electronic dampers where equipped. This kit is a practical option for owners addressing aging air suspension components on a 2003-2009 Toyota 4Runner rear or a 2003-2007 Lexus GX470 rear, as well as 2008-2009 Lexus GX470 rear models with rear air suspension.

What It Helps Address

• Rear air spring leaks or loss of air pressure
• Compressor cycling caused by failing air suspension components
• Uneven rear ride height from worn air springs
• Suspension warning lights related to air spring system faults
• Need to convert a factory air suspension to a conventional coil spring setup

Installation Notes

Verify rear fitment by year, make, model, and suspension configuration before installation. This Monroe 90022C conversion kit does not disable electronic dampers, so vehicles equipped with those systems retain that function after conversion. Mounting hardware is not listed as included, so confirm any additional service parts needed before beginning the repair. Professional installation is recommended for suspension work on Lexus GX470 and Toyota 4Runner applications.

Quality Assurance

Monroe markets this Air Spring to Coil Spring Conversion Kit as a premium suspension solution with application-specific components for the listed vehicles. Part number 90022C is engineered for the confirmed rear fitments shown above and cross-references Monroe Shocks & Struts C2410 for the same application.
