Product Details

Arnott AS-2822 is engineered as a complete rear air suspension strut assembly for the Mercedes-Benz S-Class and CL-Class platform. The design replaces the original rear left air strut with a new assembly that combines a gas-charged hydraulic damper, progressive spring rate, and air ride suspension function in one unit. Arnott assembles this part in the USA and uses a durable Continental ContiTech air spring bladder along with protective hardware such as crimping rings, seals, O-rings, and a bumpstop. The unit also omits the lower isolator seal found on the OE design, helping reduce a known failure point.

This part cross-references Mercedes-Benz OE numbers 2213205513 and 2213205713 for the same application. AS-2822 is a strong search match for rear left air suspension strut replacement on 2007-2013 Mercedes-Benz S550, 2007-2013 S600, 2008-2013 S63 AMG, and 2009-2014 CL550 models.

What This Part Helps Address

• Rear suspension sag on the left side
• Air leaks from a worn bladder or seal
• Ride-height problems from a failing air spring assembly
• Noise or harshness from a worn rear strut
• Suspension fault codes related to a damaged rear air strut

Installation Notes and Tips

AS-2822 is a direct replacement air strut that plugs into the vehicle’s electronic connector. Confirm rear left fitment before ordering, since this part is specific to the rear left position on compatible Mercedes-Benz S-Class and CL-Class sedans with AIRMATIC. Inspect the surrounding air lines, connectors, and mounting points during installation to help ensure proper operation after replacement.

Quality Assurance

Arnott manufactures this NEW replacement strut as an assembled aftermarket unit designed for the Mercedes-Benz W221 and W216 platforms. The use of a new shock absorber, Continental ContiTech air bladder, and reinforced sealing components supports consistent fit and function for the intended application.
