Front Air-Ride Conversion Kit

This Unity 31-111700 kit replaces the factory front air suspension with a passive steel-spring setup. It targets owners of select Jaguar models who want to eliminate air-ride maintenance and gain a more predictable ride. The package is built for direct fitment on the vehicles listed below. Backed by over 50 years of aftermarket manufacturing experience, Unity designs parts for trouble-free installation and long-term reliability.

Vehicle Fitment Is the Deciding Factor

The kit fits 2005-2009 Jaguar Super V8, 2006-2009 Jaguar Vanden Plas, 2010 Jaguar XJ, 2004-2009 Jaguar XJ8 and 2004-2009 Jaguar XJR. If your car is not on this list the kit will not mount correctly and cannot be adapted. Verify the exact model year and trim before ordering because no other applications are supported.

Sustained Reliability Over Time

Steel springs remove the air bags, compressor and height sensors that degrade with age and temperature cycles. The passive design delivers consistent ride height and damping response mile after mile without the risk of leaks or electronic faults that can leave the vehicle sitting low. Unity's Elite Suspension Line engineering focuses on durability so the conversion remains stable through daily driving and heavy loads alike.

It bolts to the factory front suspension locations on the 2004-2009 XJ8, XJR, 2005-2009 Super V8, 2006-2009 Vanden Plas and 2010 XJ, so no chassis modification is required.
