Restore the unparalleled comfort and stability of the Mercedes S-Class with the Biste Rear Left Air Suspension Strut. This component is engineered for maximum compatibility, designed as a single, high-quality solution for nearly every W221 chassis, regardless of whether it is a Rear-Wheel Drive or a 4MATIC All-Wheel Drive model.
By replacing a vast array of original equipment part numbers, this strut is the most efficient and reliable choice for distributors and repair shops. It eliminates the complexity of stocking multiple parts for the same application, allowing you to service a wider range of vehicles with a single, trusted component.
Key Features & Benefits:
Exceptional Versatility: A single part designed to fit both 2WD (RWD) and 4MATIC (AWD) W221 models, dramatically simplifying your inventory.
Extensive OE Cross-Compatibility: Replaces a wide range of OE part numbers, including the common 2213205513, 2213205713, and 2213201338 series, guaranteeing fitment across numerous vehicle production years and variations.
Restores Legendary Ride Quality: The internal shock absorber is precisely valved to replicate the original S-Class ride—smooth, controlled, and luxurious. It effectively eliminates sagging and restores correct ride height.
