Vehicle Fitment Guide

This complete strut conversion kit fits 2004 to 2009 Jaguar XJ8 and XJR models, the 2005 to 2009 Super V8, the 2006 to 2009 Vanden Plas, and the 2010 XJ. It is built for owners who want to replace a factory air suspension with a steel spring set-up. Buyers needing to keep the original air ride system cannot use this kit.

Pre-Installation Checks

Confirm the vehicle year and model match the listed Jaguar applications before ordering. The kit replaces both front and rear assemblies, so plan for a full four-corner conversion. No speciality tools are required for installation, but verify that existing mounting points are free of corrosion or damage.

Build Quality And Daily Use

Each strut arrives preassembled with a gas-charged cartridge, coil spring, top mount, bearing plate, bump stop, insulators and dust boot. The design restores factory ride height and bolts on directly. Converting to non-air steel springs removes the complexity and potential leaks of the original air system while delivering a consistent ride feel.
