Rear Electronic Air Strut Assembly
This rear electronic air strut assembly replaces the original suspension unit on select Mercedes-Benz S-Class models. It fits the 2006 S350, 2000-2006 S430 and S500, and 2001-2006 S600. The part is not compatible with 4Matic all-wheel-drive variants. Unity manufactures this assembly to restore factory ride height and damping control.
Brand-new replacement unit
The assembly arrives as a complete brand-new replacement rather than a remanufactured unit. It includes the electronic components required for the vehicle's air suspension control system. Unity's manufacturing experience aims to provide a trouble-free installation that matches original equipment specifications for fit and function.
Restores air suspension on non-4Matic S-Class models
This strut comfortably handles the suspension demands of the listed rear-wheel-drive S-Class sedans from 2000 to 2006. It runs out at the 4Matic boundary; buyers with all-wheel-drive versions need a different part. The unit supports the electronic air suspension system on the specified chassis codes through the 2006 model year.
