Arnott AS-2786 Air Suspension Strut - Front Left

Front Left Air Strut for Mercedes-Benz E-Class and CLS-Class

The Arnott AS-2786 is a new front left air suspension strut for select Mercedes-Benz E-Class and CLS-Class models with AIRMATIC and without 4MATIC. It replaces the original OE strut with a new, application-specific assembly built to restore ride height control, damping response, and everyday drivability.

Arnott’s NEW product line focuses on engineered aftermarket suspension replacements that follow the original vehicle layout while updating key wear components. The AS-2786 combines a custom tuned shock absorber, a ContiTech air bladder, and a CNC-machined aluminum top mount for a direct-fit front left solution on the Mercedes-Benz E320, E350, E500, E550, CLS350, CLS500, and CLS550 applications listed below.

• Front left air suspension strut for AIRMATIC-equipped Mercedes-Benz models without 4MATIC
• New custom tuned shock absorber calibrated for original ride and performance characteristics
• ContiTech air bladder protected by an aluminum can
• CNC machined top mount made from aircraft-quality aluminum
• Assembled in the USA with Arnott seals, bump stop, heavy-duty crimping rings, connector valve, and dust boot
• Air adjustable, gas charged, hydraulic internal damper, progressive spring rate
• Mounting hardware included

This Arnott AS-2786 air suspension strut is built for drivers replacing a worn front left strut on Mercedes-Benz E-Class and CLS-Class vehicles that use AIRMATIC air suspension. It is designed to address loss of ride control, uneven stance, air leaks, and harsh suspension behavior by replacing the complete strut assembly with a new unit engineered around the original fitment and suspension geometry. This part cross-references Mercedes-Benz OE numbers 2113205513 and 2193201113 for the same application.

Common Problems This Strut Can Address

• Front left corner sagging or sitting lower than the other side
• Air leaks from a worn bladder or aging seals
• Excessive bouncing, harshness, or reduced damping control
• Suspension warning lights related to air spring performance
• Uneven ride height on AIRMATIC-equipped Mercedes-Benz E-Class or CLS-Class models
