Purpose and Function of the Part

The rear tailgate gas spring is responsible for smooth lifting and stable holding of the tailgate in the open position. This component works continuously with every opening and closing, so its efficiency directly impacts user convenience and protects the tailgate hinges and mounts.

The presented gas spring is intended for the left side of the rear tailgate, which is important when selecting parts for a specific vehicle. Correct side selection ensures the original tailgate geometry and even load distribution.

Construction and Operating Characteristics

The rear tailgate gas spring in this model is designed to work with the hinges and lock, providing:

• controlled assistance force when opening the tailgate,
• motion damping in the final stage of opening,
• holding the tailgate in a stable working position,
• limiting overloads acting on the body.

Thanks to its factory fit for the Mercedes X164 body structure, the spring operates within the force range specified by the manufacturer, promoting uniform and predictable tailgate operation.

Condition, Origin, and Fitment

The offered part is a used component, sourced from a dismantled Mercedes vehicle. Such OEM components are valued for their factory fit to a specific body generation and compatibility with original mounting points. In practice, this translates to installation without modifications and maintaining the original tailgate operating characteristics.

The designation as left side facilitates correct part selection when replacing a single gas spring or a pair of components. Replacing a worn spring with an original part from the same group allows for restoring proper tailgate function without interfering with other components.

Benefits of Using an Original Rear Tailgate Gas Spring

Using a dedicated rear tailgate gas spring for the Mercedes X164 offers several practical benefits:

• increases the comfort of daily use of the trunk,
• reduces the risk of the tailgate dropping unintentionally,
• lessens the load on hinges and mounts,
• maintains predictable, repeatable tailgate operation throughout the entire opening range.

For users who prioritize the functionality of the rear of their vehicle, replacing a worn gas spring with an original part is a simple way to restore the full usability of the luggage space.
