Front Air Strut Assembly Kit for 4Matic
This kit supplies two electronic air suspension strut assemblies built to original equipment specifications for 4Matic models. It fits 2003-2005 E320, 2006-2009 E350, 2004-2006 E500 and 2007-2009 E550 vehicles. The assemblies restore smooth ride quality and structural support for the vehicle and its load.
Two Strut Assemblies Included
The bundle provides a matched pair of front units so both sides can be replaced at once. This eliminates the need to source individual components separately and helps maintain balanced damping and ride height across the front axle.
4Matic Models Only
The kit is validated solely for the 4Matic all-wheel-drive variants listed; it will not fit rear-wheel-drive versions of the same model years. Buyers with non-4Matic chassis or model years outside the 2003-2009 range must verify compatibility before purchase.

Questions about this item
How often will the electronic air strut assemblies in this kit need replacement under normal driving?
Unity designs these assemblies for long-lasting reliability, but replacement interval depends on road conditions and mileage; inspect during routine suspension service.
What component reaches its limit first when the vehicle carries heavy loads daily?
The air spring and electronic damper share the load; sustained heavy use stresses the air spring bladder and damper valving equally.
Does the compressor run louder or hotter after installing these struts on a 4Matic model?
The struts are built to OE specifications, so compressor operation remains unchanged from factory behaviour.
