Arnott AS-2788 Air Suspension Strut - Front Left

Front Left Air Strut for Mercedes-Benz AMG

Arnott AS-2788 is a new front left air suspension strut for select Mercedes-Benz AMG models. It replaces a worn OE unit with a pre-assembled assembly built to restore ride height control, damping response, and air suspension performance on the E-Class AMG platform.

Designed and assembled in the USA, this Arnott NEW line strut combines a custom-tuned hydraulic shock absorber with a ContiTech multi-ply air spring bladder, aluminum canister protection, and a CNC-machined top mount made from aircraft-quality aluminum.

Detailed Description

AS-2788 is built for drivers replacing a leaking, noisy, or uneven front left air strut on Mercedes-Benz AMG applications. The assembly uses a hydraulic internal damper, progressive spring rate, and spring-assisted air ride construction to help restore consistent front suspension control. Arnott’s NEW product line focuses on new components rather than remanufactured parts, and this unit includes long-lasting seals, O-rings, bump stop, heavy-duty crimping rings, connector valve, and a protective dust boot.

This part cross-references Mercedes-Benz OE numbers 2113205338 and 2113205538 for the same application. Arnott AS-2788 is a direct-fit replacement for the front left side on the Mercedes-Benz E55 AMG, E63 AMG, CLS55 AMG, and CLS63 AMG platforms listed above.

Common Problems This Part Can Address

• Front-left corner sagging after parking
• Air leaks from a cracked or aging bladder
• Excessive bounce or reduced damping control
• Uneven ride height or suspension warning symptoms
• Noise from a worn strut assembly or damaged boot

Installation Notes and Tips

Verify the vehicle’s front left position and OE part number before installation. Inspect the air line, fittings, and surrounding suspension components for wear or contamination before installing the new strut. A detailed installation manual is available, and proper torque procedures should be followed during assembly and final ride-height checks.

Quality Assurance

Arnott AS-2788 is a new assembly from the Arnott NEW line, designed and assembled in the USA with brand-specific seals, air spring components, and mounting details intended to support consistent fitment and suspension function on the listed Mercedes-Benz AMG applications.
