Unity Rear Right Air Spring 15-525502

This replacement air spring fits 1999-2003 BMW 5 Series wagon models equipped with self-leveling suspension. It restores the rear right corner of the air suspension system for 525i, 528i and 540i variants. The part is designed for vehicles without sport suspension.

Direct-fit design for straightforward installation

The unit bolts into the original mounting points on compatible wagons, so no fabrication or modification is required. Installers should verify the vehicle has self-leveling suspension and not sport suspension before fitting, as the spring will not suit the latter. Reusing worn mounting hardware can cause premature leakage or noise.

Maintains ride height under continuous load

The air spring supports the vehicle’s self-leveling function during extended journeys or when carrying passengers and luggage. It resists fatigue from repeated compression cycles better than aged original units. Vehicles with sport suspension or non-wagon body styles cannot use this part.
