Purpose and function in the suspension

The rubber buffer in the suspension of the Mercedes Citan W415 and Renault Kangoo is responsible for providing adequate spring support and controlling deflection under load. It operates under high-stress conditions, absorbing vibrations and limiting the transmission of shocks to the chassis.

Using the correct rubber buffer is important for:

• maintaining stable suspension height under load,
• even distribution of forces within the spring,
• reducing noise and vibration while driving with a load,
• protecting other suspension components from overloading.

Benefits of using an original rubber buffer

The original rubber buffer from this parts group has been designed for specific Mercedes Citan and Renault Kangoo models, which translates into a precise fit for the spring and mounting seats. As a result, the factory suspension characteristics are maintained, and the vehicle reacts predictably to loads and road irregularities.

Key advantages include:

• compatibility with the factory suspension system – no need for modifications or adjustments,
• consistency with other spring components,
• stable support during operation across the full range of deflection,
• reduced risk of premature wear of the spring and mounts.

Material and operational characteristics

The buffer is made of a carefully selected rubber compound, adapted to operate in conditions of varying temperatures, humidity, and contact with road contaminants. The material structure provides the elasticity needed to absorb impacts while maintaining sufficient rigidity to keep the spring in the required position.

In practice, this means:

• better control over suspension deflection under sudden loads,
• reduced risk of suspension bottoming out when fully loaded,
• more comfortable spring operation in typical urban and extra-urban conditions.

Condition and service application

The item is sourced from disassembly and is offered as a used part, allowing for economical suspension repair while maintaining original specifications. This type of rubber buffer is suitable both for replacing a single worn element and for more extensive spring maintenance in vehicles used for urban transport or delivery services.

Replacing the rubber buffer is particularly recommended when symptoms appear such as:

• excessive rear axle deflection under load,
• knocking or suspension bottoming out when driving over speed bumps,
• uneven vehicle sagging on one side.
