Purpose and function in the vehicle

The tailgate gas strut set for the Mercedes W164 is responsible for the controlled lifting and holding of the tailgate in a safe operating position. Using two matched components on the right and left sides ensures even load distribution, which reduces stress on the hinges and the tailgate lock. As a result, the mechanism operates smoothly, and the user does not need to use excessive force when opening the trunk.

Components from this group are particularly important in daily use – they are responsible for convenient access to the cargo area and the stability of the tailgate during loading. Properly selected gas struts reduce the risk of the tailgate falling unexpectedly, which improves vehicle safety.

Set construction and mounting fitment

The presented set includes a gas strut for the right side and a gas strut for the left side, which facilitates the simultaneous replacement of both components in a single service process. This approach is beneficial in terms of durability – new, evenly operating gas struts do not place one-sided stress on the hinges or tailgate mounts.

The original Mercedes origin ensures the preservation of factory geometry, mounting points, and operating characteristics. Thanks to this, installation is predictable, without the need for modifications or adjustments. The set is suitable for users who want to maintain the structural integrity of the vehicle and avoid compatibility issues.

Performance characteristics and benefits of using the set

Using a complete tailgate gas strut set in a Mercedes W164 provides a number of practical benefits:

• stable support of the tailgate in the open position,
• more predictable, smooth movement during opening and closing,
• reduction of loads acting on the hinges and the tailgate lock,
• reduction of the risk of the tailgate falling suddenly during loading.

The set is particularly useful in heavily used vehicles where the tailgate mechanism is frequently operated. Replacing both gas struts at the same time allows for restoring the even operation of the system and improving the overall comfort of using the trunk.

Product condition and economic benefits

The offered set comes from the Gas springs, locks, hinges, and other parts group and is a used item, which represents a reasonable compromise between cost and functionality. Choosing original used components allows for maintaining factory fitment while reducing expenses compared to purchasing new parts. This solution is aimed at users who want to keep their vehicle in good technical condition while ensuring rational service costs.

Integration with other body elements and the trunk area

The tailgate gas struts work with the hinges, lock, and tailgate panel, creating a cohesive system responsible for handling the cargo area. Properly selected components from this group affect loading ergonomics, daily convenience, and the overall feeling of body solidity. If you are planning a comprehensive repair or upgrade of the trunk area in your Mercedes and need other components from the same group, such as additional gas springs, locks, or tailgate hinges, check the available parts in the category Gas springs, locks, hinges, and other Mercedes parts.

Additional materials and technical knowledge

Conscious selection of body components, including tailgate gas struts, requires understanding the differences between individual design solutions used by manufacturers. In the context of comparing the approach to design and the selection of original parts, it is worth reading material discussing the differences between classic and modern designs and the role of OEM components: comparison of classic Mini and modern MINI and the importance of OEM parts.

Summary

Mercedes W164 Tailgate Trunk Gas Strut Left Right N/O/S Set x2 is a practical set for users expecting efficient, predictable tailgate operation and the preservation of factory body fitment. The original Mercedes origin, the set covering both sides, and the well-thought-out design of the lifting mechanism make this a suitable solution for both standard maintenance replacement and more extensive service work in the trunk area.
