Purpose and function of the strut

The left tailgate strut is responsible for lifting and supporting the tailgate in the open position, as well as for its smooth lowering. A properly selected component ensures:

• stable support of the tailgate in the upper position,
• controlled, predictable movement during opening and closing,
• reduction of loads acting on the hinges and other mounting elements. Thanks to its proper fit to the design of the GL X164 model, the strut works with the factory mounting system, which helps maintain the original operating geometry of the tailgate.

Compatibility with Mercedes GL X164

The presented strut has been designed for use in the Mercedes GL X164 model, taking into account the specific weight and operating range of the tailgate. Positioning on the left side of the vehicle allows for the correct distribution of forces in pair with the right strut, which affects:

• even support of the tailgate,
• increased durability of the entire lifting mechanism,
• maintaining ease of operation even with frequent use of the cargo space. Using a component that complies with the factory design standard reduces the risk of improper tailgate closing and excessive play in the system.

Performance characteristics and installation

The left tailgate strut from this offer is a used part, which in practice means a favorable compromise between cost and functionality. The component is intended for installation in place of the factory strut, using the original mounting points on the body and the tailgate. Under typical conditions, the replacement follows this pattern:

• removal of the worn strut from the mounts on the body and tailgate side,
• inspection of the mounting sockets for mechanical damage,
• installation of the used strut in the same mounting points. Such a solution allows for maintaining the factory opening range of the tailgate and predictable resistance during its lifting.

Application in the loading area

A functional strut has a direct impact on the comfort of operating the rear part of the vehicle, especially when frequently using the luggage compartment. A properly working component:

• facilitates daily loading and unloading,
• reduces the risk of the tailgate falling down on its own,
• supports safe use of the loading zone by the driver and passengers. For users who use the trunk intensively, replacing a faulty strut with a properly selected component is a practical way to restore the functionality of the tailgate.
