Detailed Description

Arnott AS-2603 is a remanufactured rear right air suspension strut engineered for Mercedes-Benz vehicles that use an OE-style air suspension setup. It is designed for models including the Mercedes-Benz S550, S600, S63 AMG, and related applications, with a center-eye body end, loop/eyelet lower mount, and stud-style upper mount. The unit uses a hydraulic internal damper, gas charge, and progressive spring rate to support stable rear suspension behavior.

This part number, AS-2603, is built around a rebuilt OE rear air strut design and uses a new Continental ContiTech air sleeve for the air spring section. Arnott’s remanufactured product line focuses on restoring original suspension function while keeping the replacement more affordable than a full new assembly. This part cross-references Mercedes-Benz OE numbers 2213205613 and 2213205813 for the same application.

What It Helps Address

• Rear suspension sag on the right side
• Uneven ride height at the rear of the vehicle
• Air spring leakage from a worn strut assembly
• Excessive bouncing or reduced damping control
• Suspension warning lights related to rear air strut failure

Installation Notes and Tips

Verify rear right fitment before installation on Mercedes-Benz CL550, S350, S400, S450, S500, S550, S600, S63 AMG, and S65 AMG applications. Confirm the OE part number, mounting style, and suspension configuration match the vehicle before replacing the strut. Inspect the air line, compressor output, and related suspension components during service to avoid repeat failures.

Quality Assurance

Arnott backs this remanufactured air suspension strut with a Limited Lifetime Warranty. The AS-2603 is rebuilt to OE-style standards and uses a new Continental ContiTech air sleeve for added component consistency in the air spring section.
