Purpose and function of the strut

The strut is responsible for the controlled lifting and lowering of the tailgate on the right side of the vehicle. A properly selected component:

• stabilizes the movement of the tailgate throughout its full range of motion,
• reduces stress on hinges and mounts,
• ensures repeatable, predictable operation of the loading system. Thanks to a design consistent with factory solutions, the strut works with existing mounts and the tailgate system without the need for structural modifications.

Benefits of using an original strut

Using a component dedicated to the Mercedes GL X164 for the right side of the tailgate allows for maintaining the original operating characteristics of the system. In practice, this means:

• proper tailgate balance – no sudden dropping or excessive resistance when closing,
• better protection of hinges and tailgate paneling against excessive stress,
• consistency with other components from the Loading tailgates group. This is particularly important in a large SUV, where the weight of the tailgate is significantly higher than in compact cars, and the loads acting on the struts are greater.

Installation characteristics

The strut is designed for installation on the right side of the vehicle, in the factory mounting points provided for the Mercedes GL X164. The design, based on the serial solution, facilitates the work of a mechanic or a person dealing with body repair because:

• it does not require adaptation of brackets or interference with the tailgate structure,
• it allows for maintaining the original opening geometry,
• it minimizes the risk of improper fitment of rear body components. The used condition of the part is a good compromise between repair cost and maintaining performance parameters close to factory standards.

Use of a pre-owned OEM component

Choosing a used tailgate strut for the Mercedes GL X164 is particularly beneficial for maintenance repairs where the price-to-quality ratio matters. An original component from the same assembly group:

• maintains compliance with the vehicle's factory specifications,
• reduces the risk of fitment issues typical of universal aftermarket replacements,
• allows for a faster and more predictable repair of the tailgate system. This solution is recommended both for workshops specializing in the Mercedes brand and for private users who want to restore full functionality to the tailgate without excessive costs.
