Product Details

Arnott’s REMANUFACTURED line focuses on rebuilding OE air suspension components with updated materials and revised sealing methods. On the AS-2540, the original epoxy-style upper seal is replaced with O-ring sealing technology to reduce the cracking and leakage issues commonly associated with aging air struts. The result is a front air suspension strut engineered for Mercedes-Benz S-Class vehicles that need restored ride height control, damping response, and air spring function. This part cross-references Mercedes-Benz 2213204913 and 2213209313 for the same application.

What This Part Helps Fix

• Front-end sagging from a leaking air spring bladder
• Air suspension warning lights caused by pressure loss
• Uneven ride height at the front of the vehicle
• Excessive bounce or reduced damping control
• Cracked upper seal areas that lead to air leaks

Proper calibration and alignment checks after installation help restore correct ride height and handling.
