Fitment and Application

Compatible with 2007-2017 Lexus LS460 models in the front and rear positions. This Arnott C-3418 conversion kit is intended for Lexus LS460 owners replacing air suspension components with a coil spring solution for a more conventional suspension layout.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

How It Works

Arnott designs these conversion kits as a direct alternative to aging air springs. The coil springs are made from U.S. steel and are engineered to deliver a stable ride while eliminating the complexity of air suspension components. For the Lexus LS460, C-3418 provides a practical path away from recurring air spring failures and toward a simpler suspension system.

Common Problems This Kit Can Address

• Air spring leaks that cause the vehicle to sit low
• Compressor cycling caused by failing air suspension parts
• Uneven ride height at the front or rear
• Warning lights related to air suspension faults
• Repeated repair costs from aging air suspension components

Installation Notes

Install on vehicles confirmed to be equipped with the listed air suspension configuration. Verify front and rear application before ordering, and inspect related suspension components such as shocks, mounts, and lines during service. Professional installation is recommended for proper suspension setup.

Quality Assurance

Arnott develops its conversion kits to replace failing air springs with a standard replacement coil spring solution. The C-3418 is engineered and tested for long-term, trouble-free use on the Lexus LS460 platform.
