Product Details

Arnott’s REBUILT line focuses on remanufactured suspension components that restore OE-style function while replacing wear items with updated parts. For AS-2394, that includes a new Continental ContiTech air spring bladder and a remanufactured strut assembly designed for front suspension use on Mercedes-Benz R-Class vehicles. The result is a front air strut that supports air-adjustable ride height and damping control while maintaining the original mounting style.

This part cross-references Mercedes-Benz OE numbers 2513203013 and 2513203113 for the same application. Use AS-2394 when replacing a worn front air suspension strut on 2006-2013 Mercedes-Benz R350, 2007-2009 Mercedes-Benz R320, 2006-2008 Mercedes-Benz R500, or 2008 Mercedes-Benz R550, front.

Common Problems This Part Can Address

• Front suspension sag from a leaking air spring bladder
• Uneven ride height at the front of the vehicle
• Loss of damping control from a worn strut assembly
• Air suspension warning lights related to front strut failure
• Harsh or unstable ride quality on Mercedes-Benz R-Class models

Installation Notes

Verify vehicle fitment by year, model, and front position before installation. Inspect air lines, fittings, and related suspension components for wear or leaks during replacement. Because this strut uses air suspension and adjustable damping, follow the vehicle service procedure for depressurizing and recalibrating the system as required.

Quality Assurance

AS-2394 is remanufactured by Arnott and backed by a Limited Lifetime Warranty. The use of a new Continental ContiTech bladder and OE-style construction supports consistent fitment for Mercedes-Benz R350, R320, R500, and R550 front suspension applications.
