Detailed Description

FCS 99066 is engineered for front suspension service on select Mercedes-Benz models with factory Airmatic systems. The listed dimensions help identify the correct strut for vehicles that require a specific compressed length, extended length, and stroke range to maintain proper ride height and suspension movement. This part number is used for 2006-2013 Mercedes-Benz R350 front applications with Airmatic and 4 Corner Leveling, 2007-2009 Mercedes-Benz R320 front applications with Airmatic and 4 Corner Leveling, 2006-2008 Mercedes-Benz R500 front applications with Airmatic and 4 Corner Leveling, and 2008 Mercedes-Benz R550 front applications with Airmatic.

Use FCS 99066 when replacing a worn front air suspension strut on Mercedes-Benz R350, R320, R500, or R550 models that match the listed factory equipment. The part number 99066 is a useful reference when verifying the correct front air strut for these chassis.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Front-end sag from a worn air strut
• Uneven ride height on Airmatic-equipped Mercedes-Benz models
• Noisy or unstable suspension movement over bumps
• Loss of controlled front suspension travel
• Ride quality issues tied to a failing front air suspension strut

Installation Notes and Tips

Verify the vehicle’s factory suspension setup before ordering. This front air suspension strut is listed for Mercedes-Benz models with Airmatic, and some applications also require 4 Corner Leveling. Match the vehicle year, model, and suspension configuration exactly to the fitment data. Confirm the front position and compare the original strut dimensions to the listed compressed length, extended length, and stroke length before installation.
