Purpose and function in the suspension system

This component works with the Airmatic system, responsible for maintaining the set vehicle height and even load distribution on the rear axle on the right side. Thanks to precise air pressure control, the air spring provides:

• stable vehicle handling at various speeds,
• compensation for trunk and passenger loads,
• increased ride comfort on uneven surfaces,
• proper integration with the electronics of the automatic leveling system.

The placement on the vehicle (rear, right side) is crucial for maintaining the correct suspension geometry and balanced operation of both rear air springs.

Benefits of using an original Mercedes component

The original Mercedes part guarantees compliance with the vehicle's factory specifications, which translates into correct air suspension performance parameters. Using an OEM component in the Airmatic system allows you to:

• maintain factory damping characteristics and ride height,
• avoid communication issues with the suspension control module,
• minimize the risk of leaks and leveling system errors,
• maintain predictable vehicle behavior in emergency situations.

For users who value comfort and safety, it is important that the automatic leveling system operates based on components designed specifically for the given model, rather than random aftermarket replacements.

Installation and operational characteristics

The air spring with air pipe for the rear right side is structurally prepared for installation in the factory mounting points of the Mercedes W164 class. Thanks to this:

• it fits original brackets and routings,
• it works with the existing pneumatic installation,
• it enables proper bleeding and filling of the system,
• it ensures correct readings for leveling sensors.

When replacing, it is recommended to check the tightness of the entire pneumatic system and verify the condition of other suspension components to fully utilize the potential of the newly installed part.

Application in service practice

This component is particularly useful in situations where symptoms such as the right side of the rear axle sagging after parking, uneven ride height, or air suspension system error messages appear. Replacing a worn air spring with a functional OEM component allows you to:

• restore even vehicle leveling,
• reduce the workload of the suspension compressor and extend its service life,
• reduce body vibrations and swaying under load,
• maintain ride comfort at a level close to factory standards.

If you are planning a comprehensive repair or upgrade of the air suspension area in your Mercedes and need other elements from the same group, such as bellows, air lines, or components working with the leveling system, check the available parts in the Mercedes automatic leveling system category.
