Purpose and function of the gas spring strut

The presented gas spring strut has been designed specifically for the tailgate of Mercedes W447 series vehicles. It is responsible for the controlled lifting and supporting of the lid, as well as its smooth lowering without abrupt movements. This component works in pairs – on the right and left sides – which allows for an even distribution of loads acting on the hinges and the tailgate structure.

Thanks to the precisely selected characteristics of the strut, opening the trunk requires less force, and the lid itself maintains a stable position in the fully open state. This is important both for daily use and for frequent loading in workshop or fleet conditions.

Construction and vehicle placement

The gas spring strut belongs to the group of components mounted directly in the rear body area, between the tailgate structure and the vehicle body. Placement on the vehicle includes the right and left side, which allows the same type of component to be used on both sides of the trunk. Such a configuration facilitates part selection and subsequent maintenance.

The telescopic design ensures linear movement of the guide, which translates into predictable operation across the full range of the tailgate opening. The construction is adapted to work with factory mounting points on the body and the trunk lid, which limits the need for additional installation modifications.

Benefits of using an original component

Using an original gas spring strut in a Mercedes W447 vehicle allows for maintaining compliance with factory design specifications. In practice, this means:

• correct lifting and lowering force characteristics of the tailgate,
• consistent operation of both sides (right and left) when replaced in pairs,
• fitment to serial mounting points without additional adaptations,
• maintaining the proper geometry of the tailgate opening.

For the user, this translates into more convenient trunk operation and a lower risk of overloading the hinges or deforming the tailgate structure. The used component also allows for optimizing repair costs while maintaining the factory-standard performance of the mechanism.

Application in service and tailgate repairs

The tailgate gas spring strut is particularly important during repairs following rear-end collisions, tailgate replacement, or when symptoms such as the lid dropping or uneven lifting occur. Replacing the component on both sides allows for restoring predictable tailgate behavior and reducing the load on other components in the rear area.

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

Additional information and technical knowledge development
