Vehicle Application and Placement

The presented shock absorber is designed for installation on the rear axle of the vehicle and can be used on both the left and right sides. This solution simplifies part selection during suspension servicing – one type of component serves both sides, making repair planning easier and reducing the risk of installation errors.

The part is dedicated to the X117 CLA250 4MATIC body, ensuring correct suspension geometry, appropriate travel, and damping characteristics tailored to the weight and load distribution of this model.

Technical and Functional Characteristics

The shock absorber in this reference operates within the multi-link rear axle system, responsible for controlling vertical wheel movement, limiting body roll, and stabilizing the vehicle's path during load changes. The design has been developed by the manufacturer with the following in mind:

• precise vibration damping for city and highway driving,
• maintaining tire grip during braking and acceleration,
• preserving acoustic comfort inside the cabin,
• compatibility with the factory settings of the Mercedes suspension system.

By being tailored to the specific 4MATIC drive configuration, the shock absorber accounts for the additional loads resulting from the presence of drivetrain components on the rear axle.

Benefits of Using an Original Shock Absorber

Using an original rear shock absorber for the CLA X117 maintains the cohesive operation of the entire suspension. In practice, this means:

• stable handling at higher speeds and on uneven surfaces,
• more predictable vehicle behavior in corners,
• even tire wear due to proper suspension travel control,
• preservation of the factory driving characteristics, without undesirable hardening or softening.

A used original part is a solution that combines cost-effective repair with maintaining proper structural compatibility for the specific Mercedes model.

Professional Installation and Part Selection

When replacing a rear shock absorber, it is recommended to simultaneously inspect other suspension components – springs, top mounts, bushings, and control arms. Proper installation requires adhering to the correct tightening sequence and performing the final tightening with the vehicle loaded to avoid stress on rubber-metal components.

To facilitate selection and compatibility verification, the product card provides information such as brand, placement on vehicle, OEM part number, interchange numbers, and SKU. This data allows mechanics and service advisors to quickly confirm compatibility with specific equipment versions.

Condition and Service Application

The presented shock absorber is a used part, making it an attractive alternative for vehicle repairs where cost optimization while maintaining original specifications is a priority. This type of component is suitable for both immediate replacement of a damaged shock absorber and for more extensive rear axle servicing involving multiple components simultaneously.
