Original OE Number: 2053200125
Product Name: Mercedes-Benz W205 C-Class Rear Left Air Spring, Rear Air Suspension Bag Assembly

Product Description
2053200125 is a dedicated rear left air spring assembly for Mercedes-Benz W205/S205 C-Class, exclusively compatible with high-end models equipped with factory Airmatic air suspension. The rear axle of W205 models bears vehicle self-weight and trunk load. Long-term continuous telescopic pressure, extreme temperature changes, rainwater, dust and sand erosion easily cause aging, hardening, cracking, bulging, delamination, slow air leakage and rapid pressure relief of the original rubber bellows.
Typical vehicle faults include rear sagging after long-term parking, low rear-left body height, frequent activation of air compressor, abnormal air suspension height alarm, reduced chassis comfort and loose rebound on bumpy roads.
This rear left air spring is 1:1 precisely molded according to original W205 factory specifications. All mounting hole positions, bellows stroke, pressure resistance and sealing structure fully match OEM standards. Adopting multi-layer reinforced weather-resistant composite rubber, it features excellent tensile resistance, crack resistance, aging resistance and temperature stability with long-lasting air tightness. It supports non-destructive in-situ replacement without drilling or modification, fully compatible with the original Airmatic intelligent air suspension system. After installation, the vehicle body height is balanced and accurate, restoring the original chassis texture and completely solving common faults such as rear sagging, air leakage and unbalanced body tilt. It is a high-quality core accessory for auto repair replacement, bulk wholesale and cross-border export.
