Product description of Mercedes-Benz W220 rear shock absorbers, combining technical characteristics, applicable models, and market supply information:

1. Core models and functions
Main models:
2203205013: Standard rear air spring shock absorber, suitable for both sides of the W220 rear axle.
Technical Specifications:
Utilises an air spring structure, providing dynamic support via an air bladder, integrated with the Electronic Body Level Control System to automatically maintain a constant height (e.g., adjusting the vehicle's height based on speed).
Features an Adaptive Damping System (ADS), which uses vertical acceleration sensors to dynamically adjust damping force in real-time, enhancing comfort and handling stability.

2. Compatible Vehicle Models
Covered Models:
Specifically designed for the Mercedes-Benz S-Class W220 chassis, including:
Models:
S280/S280L S320/S320L
S350/S350L S400/S600
S430/S430L S500/S500L
Model years: 1998–2005
3. Materials and Structure
Material composition: Metal housing, aluminium alloy struts, rubber seals, and engineering plastic connectors, ensuring lightweight construction and corrosion resistance.
Design features:
Monotube gas pressure shock absorber, providing more stable damping response.
Must be connected to the vehicle's compressed air system via pressure tubes for inflation and deflation functions.

4. Installation and Maintenance Guidelines
Installation Requirements:
Must be replaced in pairs (left and right sides simultaneously) to prevent body height imbalance.
Specialised diagnostic equipment is required to release residual pressure and recalibrate height by re-inflating (e.g., via an OBD interface connected to a diagnostic tool).
Four-wheel drive (4MATIC) versions require specific models (e.g., 2203202238), which are not interchangeable with two-wheel drive versions.
Maintenance Tips:
Check the pressure tube seals after replacement to prevent leaks;
Four-wheel alignment calibration must be performed after completion.


Key Features:

OEM-matched and precision-engineered: Specifically designed for the rear axle of the Mercedes-Benz W220 series (e.g., S320, S350, S500, S600, etc.), ensuring perfect compatibility and seamless installation.

Exceptional Shock Absorption Performance: Utilises advanced shock absorption technology and high-quality materials to effectively absorb road vibrations, significantly enhancing ride comfort, allowing you to enjoy a smooth ride on any road condition.

Enhanced Handling Stability: Optimises vehicle handling response, reduces body roll, and improves stability during high-speed and cornering manoeuvres, giving you confident control.

Durable and reliable: Manufactured using high-strength materials and subjected to rigorous quality testing, ensuring reliable performance in all climates and road conditions.

Restore driving pleasure: Replacing worn shock absorbers not only enhances driving safety but also allows you to rediscover the unique driving pleasure offered by the Mercedes-Benz W220.
