Product Identity

The Unity 31-511700 Rear Conversion Kit replaces the original air suspension on compatible Jaguar models with a passive steel-spring setup. It is built for owners of 2004-2010 Jaguar XJ8, XJR, Super V8, Vanden Plas and XJ vehicles who want to eliminate air-system maintenance.

Installation Check

Verify that the vehicle matches the listed Jaguar applications covering 2004 through 2010 model years. Confirm the rear suspension currently uses air springs before ordering, because this kit only converts air-equipped cars to a conventional coil-spring arrangement.

Sustained Use

The steel-spring design removes the compressor, air bags and electronic height sensors that can degrade over time. Once fitted, the passive suspension delivers consistent ride height and load support without the cyclic wear associated with air-pressure maintenance.
