Purpose and function in the chassis system

The described suspension assembly is dedicated to the front axle on the right side, which is crucial for proper geometry and handling stability. Combining the suspension strut with the hub and brake disc creates a rigid, precise node responsible for:

• transferring loads from the wheel to the body during driving and braking,
• maintaining the correct position of the wheel relative to the wheel arch,
• cooperating with the braking system to effectively reduce speed,
• ensuring appropriate stiffness and suspension response under typical road conditions.

Thanks to the factory design intended for the Mercedes W204 platform, the assembly maintains the correct mounting points and operating characteristics in accordance with the vehicle manufacturer's specifications.

Benefits of using a complete assembly

Using a complete, original suspension assembly with a hub and brake disc reduces the risk of component mismatch. In one installation, you gain:

• consistency of components within the suspension and braking system,
• reduction in the number of service operations during replacement,
• easier technical condition inspection during installation,
• preservation of the handling characteristics typical for mid-size Mercedes models.

This solution is particularly beneficial for post-collision repairs or major interventions in the front chassis system, where precision of fit and predictable vehicle behavior are essential.

Identification parameters and fitment

The item has an assigned OEM part number and associated interchangeable numbers, which facilitates unambiguous identification in service catalogs and parts selection systems. The presence of multiple reference numbers allows the assembly to be matched to specific equipment versions within the Mercedes W204 family, minimizing the risk of ordering errors.

Additionally, the product is marked with an individual SKU and the Mercedes brand, which supports quick searching in the store and integration with warehouse systems. The specified vehicle placement and the defined weight of the assembly are important from both a logistics and workshop planning perspective.

Performance characteristics and condition

As an item from the Suspension replacement kits category, the product is intended for service applications in Mercedes vehicles where restoring the proper operation of the front right suspension corner is required. The assembly contains key components responsible for wheel guidance and cooperation with the braking system, which has a direct impact on safety and driving comfort.

The used condition means that the part has been removed from a vehicle and verified for further operational suitability. This solution allows for economical repair while maintaining the original design and geometry intended by the vehicle manufacturer.
