Unity Rear Air Spring Kit

The Unity Rear Air Spring Kit is a suspension replacement set for specific BMW models. It contains two air spring bags and an air suspension compressor. The kit is designed to restore the rear air suspension system on compatible vehicles. It targets owners of the listed BMW saloons who need to replace worn or failed suspension components.

Fits 1999 to 2003 BMW 5 Series saloons

This kit fits 1999 to 2003 BMW 528i, 2001 to 2003 BMW 525i and 1999 to 2003 BMW 540i models. Fitment is limited to wagon models equipped with self-levelling suspension. Vehicles with sport suspension are excluded from this application. Buyers with sport suspension or non-wagon body styles cannot use this kit.

The bundled compressor and pair of air spring bags provide the main components required for a complete rear air suspension refresh. Having both parts in one package simplifies the restoration process. No additional software or electronic modules are included with this mechanical kit.

Questions about this item

Will this rear air spring kit work with the original self-leveling suspension on my 2001 BMW 525i wagon?

Yes, the kit fits 2001-2003 BMW 525i wagon models equipped with factory self-leveling suspension, excluding sport suspension variants.

How can I verify the air compressor and both air spring bags are functioning correctly after installation?

After fitting, the compressor should pressurise the system, the rear ride height should rise to the normal level and remain stable, and no warning lights should appear on the dashboard.

Does the box contain both rear air spring bags and the air suspension compressor, or must I buy the compressor separately?

The kit includes two suspension air spring bags and the air suspension compressor together, so no separate compressor purchase is needed.
