Air Spring for Mercedes ML-Class W164 Rear air Balloon Spring 1643200625
Restore factory-level ride comfort, stability, and self-leveling performance to your Mercedes-Benz ML-Class (W164) with this high-quality rear air spring, designed as a direct-fit replacement for OEM part number 1643200625. Also known as an "air balloon spring" or air suspension bellows, this component is essential for vehicles equipped with AIRMATIC or standard air suspension systems.
Specifically engineered for the Mercedes-Benz M-Class (W164) 2006–2011, including models such as ML320, ML350, ML450, ML500, ML550, and ML63 AMG, this rear air spring ensures proper ride height, smooth damping response, and improved handling by maintaining consistent air pressure in the suspension system.
Over time, factory air springs can develop cracks, leaks, or bulges due to age, temperature extremes, and road conditions. Replacing worn air springs with this premium aftermarket unit eliminates sagging, uneven stance, and “check suspension” warnings—returning your SUV to optimal driving condition.
This air spring is built using multi-layer reinforced rubber (similar to Goodyear or Continental OE specifications), with a durable inner airtight bladder and UV-resistant outer boot. It is compatible with both standard air suspension and AIRMATIC systems—but not suitable for vehicles with ADS (Adaptive Damping System) dampers unless specified.
