Mercedes CLS W219 Spring Trunk Lid Boot Tailgate Tension A2197570029

Mercedes CLS W219 Spring Trunk Lid Boot Tailgate Tension is an original component of the trunk lid lifting mechanism, designed for installation in the rear part of the vehicle body. Thanks to its precise fit to the CLS W219 model design, it ensures stable support for the lid and predictable, controlled operation during opening and closing. This is a practical solution for users who expect consistent performance, safety, and compliance with factory Mercedes standards.

Purpose and vehicle placement

The spring is a component of the trunk lid lifting system in the Mercedes CLS W219 model, operating in the rear zone of the body. It can be used on the right or left side, depending on the vehicle configuration and the structural design used. Such placement allows for even load distribution and correct guidance of the lid throughout its entire range of motion.

Thanks to its dedicated design for a specific CLS generation, the spring works in conjunction with the hinges and other mechanism components, which translates into smooth trunk lid operation and reduces the risk of the lid falling uncontrollably.

Technical and functional characteristics

The trunk lid spring is responsible for compensating for the weight of the lid and assisting in its lifting. In practice, this means that the user feels less resistance when opening, and the lid itself stays in the upper position without the need for additional support. The component has been designed with the following in mind:

• maintaining appropriate lid support force throughout the entire range of operation,
• stable cooperation with hinges and mounts in the rear part of the body,
• maintaining repeatable performance characteristics under typical operating conditions.

A properly selected spring reduces the stress on the mounts and hinges, which can positively affect the durability of the entire trunk opening system.

Component condition and service application

The offered spring comes from the Trunk lids and rear parts category and is intended for service and repair applications in Mercedes vehicles. It will work well both when replacing a worn component and when restoring full lid functionality after body and paint repairs in the rear part of the vehicle.

Selecting the right spring for a specific CLS W219 unit is important from the point of view of operational safety – a spring that is too weak or unsuitable may cause the lid to fall, while an incorrectly selected operating characteristic may make it difficult to close. Using a dedicated component allows you to maintain the factory operating standards of the trunk mechanism.

Integration with other rear body components

The spring works with hinges, mounts, and other components of the trunk lid opening system. During post-accident repairs or when replacing several elements at once, it is worth paying attention to:

• consistent operation of both sides of the mechanism (right/left),
• condition of hinges and mounting points in the body,
• correct lid guidance throughout the entire range of motion.

This approach facilitates the restoration of the correct lid operating geometry and minimizes the risk of subsequent play, rattling, or uneven closing.

If you are planning a comprehensive repair or upgrade of the rear body area in your Mercedes and need other elements from the same group, such as lid hinges, actuators, or additional supports, check the available parts in the Mercedes trunk lids and rear parts category.

Technical support and knowledge about used parts

When selecting used body and mechanical components, it is worth relying on proven sources and the experience of premium manufacturers.
