Purpose and function in the vehicle

The trunk lid gas spring in the Mercedes CLK A209 model is responsible for assisting the movement of the lid in the rear of the vehicle. Thanks to properly selected operating parameters, this component:

• facilitates opening the lid without excessive force,
• stabilizes the position of the open lid, reducing the risk of it falling unexpectedly,
• ensures predictable, repeatable operation under typical operating conditions.

Its placement in the rear body area means the gas spring works in direct conjunction with the hinges and the lid lock, influencing the comfort of using the luggage compartment.

Technical characteristics and compatibility

The presented gas spring belongs to the group of components responsible for the mechanical support and guidance of the trunk lid. As a part from the Gas springs, locks, hinges and other parts family, it works with other components of the opening system to create a cohesive, factory-spec set. The product has a dedicated OEM part number and associated interchangeable numbers, which facilitates the selection of the correct variant for a specific body configuration.

The appropriate working length, gas spring force, and mounting method are adapted to the geometry of the trunk lid in the Mercedes CLK A209, which allows for maintaining the correct opening angle and smoothness of movement without the need for body modifications.

Condition, origin and advantages of using a used part

The offered gas spring is a used component, sourced from the dismantling of a Mercedes vehicle. This type of component, while maintaining proper operating parameters, represents a cost-effective solution compared to new replacements, while allowing the vehicle's original design specifications to be maintained.

The main benefits of using an original, used gas spring include:

• maintaining factory fitment to the lid and hinges,
• no need for modifications to mounts or body geometry,
• more predictable behavior compared to generic replacements with uncertain parameters.

Operation, safety and comfort of use

A functional trunk lid gas spring has a direct impact on the safety of operating the rear of the vehicle. A worn-out component can cause uncontrolled falling of the lid, difficult opening, or uneven operation, which reduces user comfort. Replacing it with a properly selected gas spring restores:

• stable support of the lid in the open position,
• smooth, predictable movement during opening and closing,
• more ergonomic use of the luggage space.

For users who frequently use the trunk – e.g., for daily commutes, trips, or working with a large amount of luggage – a functional gas spring provides significant functional support.
