Product Details

AS-3408 is a direct-fit air suspension strut assembly for the front right side of compatible Mercedes-Benz SUVs and crossovers. Arnott’s NEW product line focuses on engineered replacement suspension components, and this assembly uses Tier 1 materials to match the demands of air ride systems. The design combines an air spring and shock absorber in one unit to help maintain proper ride height, steering feel, and road control on vehicles such as the Mercedes-Benz GLE350, GLE400, GL450, and ML350. This part number, AS-3408, is built for applications that require Airmatic and ADS functionality.

This part cross-references Mercedes-Benz OE numbers 1663201413 and 1663205266 for the same application.
