Yes, that’s correct. The LM2003907 is an improved version of the A9073204701 air spring. It’s worth noting that this updated variant has two main advantages that significantly simplify installation and maintenance, especially when compared to the original Mercedes-Benz part number.
Improvements and Advantages
* Easier Installation: The new model is designed for quicker and simpler installation, reducing the time spent and potential errors. This is particularly relevant for service centers.
* Air Line Seal Check: One of the biggest improvements is the ability to check if the air line is connected securely. This helps prevent pressure leaks that can cause future problems and ensures the system operates efficiently and reliably.
If you have more questions about air suspension, feel free to ask. As you know, „Luft Master” is a factory and service center for airmatic air suspension, so I have a lot of information in this field.
