Purpose and vehicle placement

The presented seal is dedicated to the rear body section of the Mercedes W164 class and can be used on both the left and right sides. Its placement in the rear door area allows for effective sealing of the passenger entry zone and the luggage compartment, which is important for acoustic comfort and interior protection.

The black color of the seal is consistent with the factory body styling, allowing the component to integrate harmoniously with the body lines and other rear vehicle components.

Technical and functional characteristics

The rear axle door seal for the Mercedes W164 has been designed as a flexible element that adapts to the shape of the door frame and adjacent surfaces. Its purpose is to:

• limit the ingress of water and moisture into the vehicle interior,
• reduce wind noise while driving,
• stabilize the door closure in the rear body section,
• protect the body edges against minor mechanical damage.

Thanks to the use of original geometry, the seal works with factory mounting points and the door line, which facilitates installation and ensures proper fit along the entire perimeter.

Condition of the item and benefits of using a used part

The offered seal is a used item, sourced from dismantling, which allows for an economical repair of the rear body zone while maintaining the manufacturer's original specifications. Choosing a second-hand part is a cost-effective solution that also allows for maintaining material and structural consistency with other body components.

Using an original seal in good technical condition is particularly important in cases of door leakage problems, noise appearing at higher speeds, or visible signs of wear on the old component.

Application in the rear body zone and selection of other components

The rear left/right door seal works with the tailgate and other rear body components, affecting the overall tightness and comfort of vehicle use. Replacing this element is recommended during any major intervention in the rear door area or when renovating the luggage zone to avoid subsequent problems with moisture and corrosion.

If you are planning a comprehensive repair or upgrade of the rear body zone in your Mercedes and need other elements from the same group, such as seals, covers, or fasteners, check the available parts in the Mercedes Tailgates and rear parts category.

Support for upgrades and retrofitting

When replacing the rear door seal, it is worth considering a broader equipment upgrade, especially if the vehicle is being retrofitted or undergoing a thorough renovation. In such cases, a retrofit approach based on selecting appropriate elements from higher equipment versions can be helpful.
