Front Right Electronic Air Strut Assembly

This Unity 28-113702 assembly replaces the front right air strut on select Mercedes-Benz models. It is built for 2009 to 2013 CL550, 2012 to 2013 S350, 2008 to 2011 S450, and 2007 to 2013 S550 vehicles. The part restores factory ride height and electronic damping control.

Excludes Airmatic Suspension Systems

This unit does not fit vehicles equipped with Airmatic suspension. Buyers must verify their specific suspension type before ordering. The assembly is designed for standard electronic air suspension configurations only. Installation on incompatible systems will not function correctly.

Replaces Worn Original Equipment Struts

The assembly upgrades from a leaking or failed original strut that causes sagging or warning lights. It restores proper ride quality and sensor communication. The jump is worth it when the original unit no longer holds pressure or triggers fault codes.
