Purpose and fitment

The presented rear right door has been designed specifically for the Mercedes CLA C117 body, maintaining factory geometry and mounting points. Its placement on the rear right side of the vehicle ensures full compatibility with the original hinges, lock, window, and seals intended for this model.

By maintaining OEM construction, the door works in harmony with the factory lines of the sills, pillars, and roof, which translates into proper gap alignment, stable closing, and correct operation of the opening and locking mechanisms.

Color and paint finish

The component is finished in Kosmos Cosmic Black Metallic, characteristic of many Mercedes CLA C117 configurations. The metallic black provides an elegant, understated look and effectively masks minor operational dirt, which is practical for daily use.

To maintain visual consistency of the bodywork, it is recommended to verify the shade match with the remaining body panels and – if necessary – have a professional painter perform a color correction, especially in the case of post-accident repairs covering a larger area of the vehicle's side.

Operational characteristics and installation

The rear right door for the CLA C117 is a key element of the side body structure, influencing passenger protection, body rigidity, and interior acoustic comfort. A correctly selected and installed panel allows you to:

• restore the vehicle's side line after a collision or corrosion of the original component,
• ensure proper seal adhesion and reduce noise and wind gusts,
• maintain correct operation of the lock, handle, and window mechanism on the rear passenger side.

Installation in a specialized body and paint shop is recommended to ensure proper door alignment relative to the sills and pillars, hinge adjustment, and even gaps along the entire height of the door opening.

Benefits of using original Mercedes doors

Using original rear right doors for the CLA C117 allows you to maintain factory body parameters without the need for structural modifications. This solution is particularly beneficial for post-accident repairs, where precise fitment, predictable material behavior, and compliance with the manufacturer's service documentation are essential.

Choosing a component from the Doors and door panels category dedicated to Mercedes reduces the risk of adjustment problems, leaks, or accelerated corrosion in the sill and pillar zones, and also facilitates future vehicle resale by maintaining a consistent appearance of the side bodywork.

If you are planning a comprehensive repair or upgrade of the side body area of your Mercedes and need other components from the same group, such as outer skins, inner reinforcement panels, or additional mounting panels, check the available parts in the Mercedes Doors and door panels category.

Additional operational tips

When replacing the door, it is worth paying attention to the condition of the seals, hinges, and fasteners to maintain proper tightness and acoustic comfort after installation.
