Rear Left Air Spring for Mercedes-Benz

The Unity 15-512701 rear left air spring is a new replacement component designed to restore the air suspension system on specific Mercedes-Benz models. It targets owners and technicians who need to replace a failed or leaking air spring to regain proper ride height and comfort.

Replaces Worn Factory Air Springs

This part replaces the original equipment air spring on the rear left corner when the factory unit develops leaks, cracks or no longer holds pressure. The jump is worth it when the vehicle sits low on one corner, the compressor runs excessively or a suspension fault warning appears.

Fits Listed Mercedes Models Only

The spring fits 2003-2011 Mercedes-Benz models including the CLS550, E320, E350, E500, E55 AMG, E550 and E63 AMG as detailed in the fitment list. It is not suitable for vehicles outside this application range, for the rear right position or for any front suspension location.
