Unity Rear Air Spring 15-512900

This replacement air spring restores the air suspension system on select Mercedes-Benz GL-Class and ML-Class models from 2005 to 2016. It is designed for owners and technicians who need a direct-fit part to regain proper ride height and comfort.

Fits Airmatic models with X164 chassis code 214 only

The part is limited to vehicles equipped with the standard Airmatic suspension. It does not fit models equipped with Active Dampening Suspension (ADS) or any AMG variants, so verifying the exact suspension type before purchase is essential.

Direct-fit design for trouble-free installation

Unity states the spring is made for a straightforward installation that restores a safe and comfortable air ride. The main risk is ordering the wrong unit for an ADS or AMG vehicle, which this part does not support.
