Achieve Perfect Symmetry: The Final Piece of Your W221 Rear Suspension Repair
A single worn strut compromises the entire axle. To fully restore the integrity, safety, and signature comfort of a Mercedes S-Class, suspension components must be replaced in pairs. This Biste Rear Right Air Strut is the exact match for the Rear Left strut, designed to bring perfect balance back to the W221's rear axle.
By installing this strut alongside its left-side counterpart, you ensure symmetrical damping rates, uniform ride height, and predictable handling. This eliminates the risk of uneven tire wear, vehicle instability, and customer comebacks. Engineered for the same broad range of 2WD and 4MATIC models, it is the professional's choice for a job done right.
Key Features & Benefits:
The Professional's Choice for Paired Replacement: Designed to be installed with the corresponding Rear Left strut to restore perfect rear-axle balance and vehicle dynamics.
Universal W221 Rear Fitment: A single, versatile part engineered to fit both 2WD (RWD) and 4MATIC (AWD) models, simplifying inventory and guaranteeing application coverage.
Restores Flawless S-Class Comfort: The precision-valved internal damper absorbs road imperfections flawlessly, eliminating rear-end sag and returning the vehicle to its luxurious, factory-new ride quality.
Direct OE Replacement: A bolt-on solution that directly replaces OE part numbers 2213205613 and 2213202213 (including 'A' prefix variants), for a hassle-free installation.
TS16949 Certified Quality: Manufactured in a facility adhering to the strict TS16949 automotive quality standard, guaranteeing reliability and long-term performance that you and your customers can trust.
