Rear Air Strut Assembly Kit for Mercedes-Benz CL &

This kit contains two electronic rear air strut assemblies designed to replace faulty original units on specific Mercedes-Benz models. It covers the 2007 to 2013 CL550, CL600, CL63 AMG and CL65 AMG as well as the 2012 to 2013 S350, 2010 to 2013 S400 and 2008 to 2011 S450. The assemblies restore the factory air suspension function and ride quality.

Built to OE specifications for direct fitment

Each strut is manufactured to original equipment dimensions and electronic interface requirements, allowing a trouble-free installation without modification. The kit bundles both left and right rear units, so the axle is serviced completely in one procedure. Unity's aftermarket suspension experience underpins the construction for long-term durability under vehicle load.

Two complete assemblies included for full axle

The package supplies both rear struts, eliminating the need to source units separately and ensuring matched damping characteristics across the axle. This reduces installation time and helps maintain balanced handling and ride height. No additional electronic modules or sensors are included; the assemblies connect to the vehicle's existing air suspension control system.
