Purpose and fitment

The arm has been designed specifically for the Mercedes C-Class W203 generation and the CL203 coupe version, taking into account the geometry of the windshield and the operating characteristics of the factory wiper mechanism. Positioning on the right side of the vehicle guarantees proper blade pressure against the glass and the correct operating range, in accordance with the manufacturer's factory specifications.

Thanks to a design consistent with the solutions used by Mercedes, the component maintains appropriate rigidity while not excessively loading the wiper mechanism axle. This results in smooth system operation and reduces the risk of blade vibration when driving at higher speeds.

Construction and technical properties

The right wiper arm utilizes the factory mounting geometry for the mechanism, which facilitates installation and ensures correct positioning relative to the windshield. The applied arm profile allows for even distribution of pressure force along the entire length of the blade, which promotes effective removal of water and debris.

The component belongs to the Wiper arms group, so its construction is optimized for resistance to dynamic loads, operation in a wide temperature range, and exposure to moisture. A properly selected operating angle and resting position minimize the risk of collision with the hood or windshield seals.

Condition, installation, and operation

The offered arm is a used component, which allows for an economical repair of the wiper system while maintaining the original manufacturer's specifications. This is a practical solution in situations where the existing arm is bent, corroded, or no longer provides proper blade pressure against the windshield.

Installation is typical for this type of component – after correctly setting the position of the arm relative to the windshield and the mechanism, it is possible to quickly restore full wiper functionality. A properly selected arm reduces blade wear, improves system comfort, and increases driving safety in the rain.

Why choose an original Mercedes arm

Choosing an original wiper arm for a Mercedes means maintaining the factory operating characteristics of the system, without the need to adapt universal replacements. Precise fitment for the specific model translates into the correct blade movement path, no rubbing against the edges of the windshield, and stable operation throughout the entire range of motion.

Using components consistent with the manufacturer's design also helps to reduce the load on the wiper mechanism and motor, which can extend their durability. This is particularly important in vehicles used daily, where the wiper system operates frequently and in varied weather conditions.

If you are planning a comprehensive repair or upgrade of the windshield visibility zone in your Mercedes and need other components from the same group, such as additional arms, mounts, or elements that work with the blades, check the available parts in the Mercedes Wiper arms category.
