Purpose and function of the component

The described pneumatic strut is designed to work on the right side of the vehicle, where it is responsible for assisting in opening and keeping the tailgate in a stable position. Thanks to properly selected factory parameters, it works with the hinges and lock, reducing structural stress and improving the comfort of operating the rear part of the body.

As an original Mercedes brand component, the strut maintains the correct force and stroke characteristics, which is particularly important for the heavier, more complex tailgates used in modern bodies. A correctly selected component minimizes the risk of the tailgate sagging and the uneven operation of the entire mechanism.

Construction and mounting parameters

The tailgate pneumatic strut uses compressed gas to generate lifting force, which allows for smooth opening and closing of the lid without placing excessive strain on the user. The design is adapted for installation in factory mounting points on the right side of the body, ensuring the correct operating geometry of the entire system is maintained.

The component is compatible with original brackets and joints, which facilitates replacement in service conditions. Using a dedicated strut on the passenger side allows for maintaining the symmetry of operation on both sides of the tailgate, which translates into even load distribution and longer hinge life.

Condition, origin, and identification

The product comes from dismantling and is offered as used, which is a cost-effective solution while maintaining the manufacturer's original specifications. Factory markings and the OEM part number allow for unambiguous identification and matching to the specific X118 body version, and the available interchangeable numbers allow for verifying compatibility with other references used by the manufacturer.

Additionally, the product description provides an SKU, which facilitates order processing and communication with the sales department, and information about the placement on the vehicle eliminates the risk of confusion between the left and right sides when selecting parts.

Application in the Tailgates and rear parts system

The pneumatic strut on the right side is a key element of the entire rear lid assembly, working with the lock, hinges, and any additional struts on the opposite side. A properly functioning component:

• stabilizes the movement of the tailgate during opening and closing,
• limits impacts and structural stress,
• improves the safety of using the rear part of the vehicle,
• increases the comfort of access to the luggage space.

By maintaining the factory operating characteristics, replacing a worn strut with an original component allows for restoring the correct operation of the entire system without the need for body modifications.

Selection and technical support

When selecting a pneumatic strut for a specific vehicle, it is worth paying attention to the body version, equipment, and mounting side. In case of doubt, the manufacturer's markings and information from the service documentation will be helpful, allowing you to confirm the full compatibility of the part with the given model.

If you are planning a comprehensive repair or modernization of the rear body area in your Mercedes and need other elements from the same group, such as tailgate hinges, locks, or additional supports, check the available parts in the Mercedes Tailgates and rear parts category.

Practical service tips

When replacing the strut, it is recommended to check the condition of the mounts, hinges, and other cooperating elements to avoid uneven tailgate operation. In the case of heavily used vehicles or those after rear-end collisions, it is also worth verifying the geometry of the mounts, which will allow for maintaining the correct opening and closing line.
