Detailed Description

Arnott C-3417 is a suspension conversion solution for Jaguar XJ owners who want to replace the original air suspension system with a conventional coil spring arrangement. This kit is engineered for the 2010-2019 Jaguar XJ and is designed around the X351 chassis, with front and rear coverage for the listed application. The conversion uses a monotube shock paired with steel springs to provide a direct replacement path away from air suspension components.

This part number, C-3417, is a practical option for drivers seeking a standard replacement suspension setup on the Jaguar XJ.

What This Kit Helps Address

• Failed air springs on a Jaguar XJ
• Compressor-related suspension warning lights
• Air suspension leaks that affect ride height
• Repeated air suspension maintenance on X351 chassis vehicles
• Dashboard suspension fault messages after conversion

Installation Notes and Tips

Compatible With 2010-2019 Jaguar XJ, front and rear. Verify the vehicle is equipped with the X351 chassis before ordering. The Electronic Bypass Module is part of the conversion strategy and is used to disable suspension warning indicators after the air suspension system is removed. Because this is a suspension conversion, proper inspection of mounting points, ride height, and related suspension components is recommended during installation. Part number C-3417 should be matched to the exact vehicle application before service begins.
