Rear Conversion Kit for Mercedes Wagons

The Unity 30-513100 kit converts air suspension to passive coil springs on Mercedes E-Class wagons without active damping. It fits 2003 to 2005 E320 models, 2006 to 2009 E350 models and 2004 to 2006 E500 models. This product is not for sedan owners or vehicles equipped with active damping systems.

Sustained Reliability Over Time

The passive coil-spring design eliminates air leaks and compressor wear that develop during extended use. Unity builds these components to withstand repeated suspension cycles without the degradation common to air bags. The kit is not for drivers who want to retain adjustable ride height or automatic load-leveling functions.

Straightforward Retrofit Installation

The kit is engineered for a trouble-free installation using existing mounting points on compatible wagons. No fabrication or wiring modifications are required for the listed applications. It is not for vehicles outside the specified model years or for owners unwilling to disable the original air-suspension warning lights.

Questions about this item

Does the Unity 30-513100 Rear Conversion Kit generate any noise or heat during daily driving?

The kit replaces the air suspension with passive steel springs, so it has no compressor, pump or electronic components that could produce noise or heat while the vehicle is running.

What existing suspension components must the car already have for this kit to install correctly?

The vehicle must be a wagon without an active damping system and must retain its original shock absorbers, spring seats and mounting hardware for the conversion to bolt on.

Will the kit work alongside the original electronic suspension controller on a 2006 Mercedes E350 wagon?

The kit is designed for models without active damping, so the factory electronic controller will not be used; the conversion removes the air bags and relies solely on the new steel springs and existing passive dampers.
