The RENNtech Hand-Held Suspension Module (HSM) is designed to work with the CLS AMG 53 equipped with the Mercedes Airmatic Suspension.The unit allows the user to have full control over all four corners of the vehicle’s suspension and adjust in 1mm increments.

The HSM comes pre-loaded with a RENNtech lowering setting. User can load their custom setting onto the HSM to set the vehicle to their preferred ride height.

The desired lowering setting will be loaded onto the vehicle via the ODB2 port in the footwell of the car. After plugging the HSM into the ODB2 port, the user can toggle a switch to load the factory or the adjusted ride height. After a few seconds, the new setting is uploaded and the car will adjust to the new height.

The factory setting will always be stored on the HSM and the user can set the vehicle back to the factory setting.

Once the settings are loaded, simply unplug and store for future use.

With the newest update to our HSM, the user is now able to adjust the suspension settings directly in the on-board command system in their Mercedes. After plugging the HSM into the OBD2 port, the #RENNtech HSM Screen will appear on the Mercedes Command screen. After changing and saving the settings, the module can be unplugged and the screen goes back to the regular Mercedes menu.

No tools, laptop or tablet needed. Full Plug'n'Play Solution.


All RENNtech HSMs are adjustable via USB using either Windows or Android OS.The software allows the user to adjust the ride-height at each corner in 1mm increments independently. The software also has three locations where the user can store pre-configured suspension setups for quick changes. Please note, the following models do not support COMMAND integrationMY 2020+ 167 GLS / GLE -Class | MY 2020+ 253 GLC.
