Technical and Functional Characteristics

The shock absorber belongs to the group of components responsible for body movement control and maintaining constant tire contact with the road surface. A properly selected and functional component:

• limits body roll over uneven surfaces and during sudden maneuvers,
• supports even tire wear,
• improves the effectiveness of the braking system by ensuring stable wheel contact with the road,
• increases driving comfort through smoother vibration damping.

As a part from the Shock Absorbers and Struts category, this product works with other suspension components, forming a cohesive system responsible for safety and predictable handling.

Brand, Origin, and Condition

The shock absorber comes from the vehicle manufacturer, meaning it is a part that conforms to original factory construction standards. This ensures correct mounting points, geometry, and performance characteristics tailored to the specific model. The product is used, which allows for an economical suspension refresh while maintaining the original assembly specifications.

Suspension System Application and Part Selection

Replacing the rear shock absorber in a Mercedes W212 is particularly important when symptoms such as extended braking distances, excessive body roll, or uneven tire wear appear. Installing a properly selected component on the left and right sides of the rear axle helps restore predictable vehicle behavior and improve driving comfort on longer journeys.

When selecting this model, it is advisable to pay attention to compatibility with the vehicle manufacturer's designations and the placement parameters on the vehicle. The presence of dedicated part numbers and interchangeable numbers facilitates verification of compatibility with the specific body and engine version.
