Purpose and function in the vehicle

The presented gas strut operates in the rear section of the body on the left side, responsible for the controlled opening and closing of the tailgate. The component works with the hinges and other lifting system parts, ensuring:

• smooth lifting of the tailgate without jerking,
• keeping the tailgate in a stable operating position,
• damping the movement when closing, which reduces mechanical stress.

By being matched to the specific mounting axis on the left side, the strut maintains the correct operating geometry and evenly distributes the forces acting on the tailgate structure.

Original origin and fitment for Mercedes X166

The strut has been designed for the X166 series body, which translates into precise fitment to factory mounting points. This means there is no need for modifications, drilling, or the use of additional adapters – the component works with the original brackets and tailgate mechanism.

As a part from the Loading hatches group, the component is optimized for the weight and dimensions of the tailgate in this model, which allows for maintaining the correct lifting force characteristics and trunk handling comfort even with frequent use.

Characteristics of the used component

The offered strut is a used part, which in practice means the possibility of achieving a favorable price-to-quality ratio while maintaining the original manufacturer's specifications. This type of part is particularly attractive in situations where:

• the existing strut has lost pressure and does not hold the tailgate,
• the tailgate drops automatically or requires excessive force to lift,
• it is necessary to replace only one component on the left side.

Choosing a used OEM component allows for reducing repair costs while maintaining compatibility with the factory lifting system.

Benefits of using an original strut

Using the correct strut on the left side of the tailgate in a Mercedes X166 translates into a number of practical advantages:

• Operational safety – reducing the risk of the heavy tailgate suddenly falling on the user or cargo.
• Trunk handling comfort – predictable, repeatable tailgate movement when opening and closing.
• Protection of hinges and mounts – properly selected force characteristics reduce structural stress.
• Consistency with the factory design – no interference with the body and preservation of the original tailgate operating geometry.

This solution is particularly recommended for repairs performed in accordance with the manufacturer's guidelines, where maintaining the original operating parameters of the mechanism is essential.

Support with selection and further system expansion

If you are planning a comprehensive repair of the rear loading area, it is worth considering verifying other elements of the tailgate lifting system as well.
