Product Identity

This Unity rear air spring carries part number 15-571000 and fits 1999-2004 Land Rover Discovery models. It replaces the original air spring to restore factory ride height and load-leveling function. The component is manufactured by Unity, a supplier with over 50 years in the aftermarket suspension business.

Installation Context

The spring bolts into the existing rear air-suspension mounts and connects to the vehicle's air lines and compressor system. No frame modifications or additional brackets are required for fitment. A working compressor, valve block and leak-free air lines are needed for the system to operate correctly after replacement.

Upgrade Perspective

This part replaces a cracked, leaking or collapsed original air spring that causes sagging, compressor over-run or fault codes. The repair is worth doing when the vehicle sits low at the rear, the compressor runs excessively or a suspension warning appears. It does not address failures in the compressor, valve block, height sensors or air lines themselves.

Questions about this item

What is the expected service life of this Unity rear air spring under continuous load on a Discovery?

Unity has over 50 years of aftermarket suspension experience and designs parts for long-lasting reliability, but no specific mileage or time rating is published for this air spring.

Does the air spring generate noticeable noise or heat during daily driving on a 1999-2004 Land Rover Discovery?

The unit is a passive rubber-and-metal spring; it has no moving electrical parts, so it produces no operational noise or heat beyond normal suspension articulation.

Must the Discovery already have factory air suspension for this rear air spring to install and function?

Yes, this replacement air spring is made for the original air suspension system on 1999-2004 Land Rover Discovery models and requires that system to be present.
