Purpose and Technical Function

The tailgate gas strut is responsible for the controlled lifting and maintenance of the rear lid in a stable working position. In conjunction with the hinges and lock, it forms a cohesive lifting system that:

• relieves the user when opening the tailgate,
• ensures smooth, predictable movement without jerking,
• keeps the tailgate securely in position during loading and unloading.

By maintaining the parameters of the factory actuator, the system operates in accordance with the manufacturer's design intentions, which translates into comfort and repeatable performance.

Compatibility and Fitment

The offered part comes from the OEM parts family of the Mercedes brand, which means a perfect fit for the geometry of the hinges, mounting points, and the tailgate's operating characteristics in the W169 body. The strut's design is prepared for installation in factory sockets, without the need for modifications or adaptations.

The presence of dedicated interchangeable numbers allows for precise verification of compatibility with a specific vehicle configuration, and the use of an original solution minimizes the risk of improper pressure or insufficient tailgate support.

Performance Characteristics and Benefits

The tailgate gas strut in this version provides balanced performance characteristics, tailored to the weight and kinematics of the rear lid. In practice, this means:

• controlled tailgate opening without excessive acceleration,
• stable holding in the open position, even with frequent use,
• reduced stress on hinges and mountings.

Choosing an original actuator from this group allows for consistent operation of the entire tailgate system, which is important for both ergonomics and body durability.

Condition and Service Application

The item is offered as a used part, making it an attractive service solution for situations where replacing a worn actuator is necessary while maintaining reasonable repair costs. This type of component is particularly useful for:

• loss of tailgate support force (sagging, failure to open fully),
• uneven operation of the lifting system,
• servicing the rear lid system after bodywork and paint repairs.

Using a part from the same construction group allows for the restoration of correct tailgate functionality without interfering with other system components.

If you are planning a comprehensive repair or upgrade of the rear body area on your Mercedes and need other parts from the same group, such as actuators, hinges, or tailgate mounts, check the available parts in the Mercedes Tailgate and Rear category.

Technical Support and Ecological Aspects

Choosing a used tailgate gas strut aligns with the approach of reusing functional components, which reduces waste and raw material consumption.
