Detailed Description

Arnott C-3272 is an air spring to coil spring conversion kit engineered for select Mercedes-Benz W221 chassis vehicles with Airmatic and ADS, including 4Matic-equipped models. The kit is built around steel compression springs and passive suspension components to replace the factory air-assisted setup on both the front and rear of the vehicle. Arnott’s NEW product line focuses on replacement solutions for suspension service, and this kit follows that approach with a standard replacement design.

This part number, C-3272, is listed for 2007-2013 Mercedes-Benz S550, 2008-2011 Mercedes-Benz S450, 2012-2013 Mercedes-Benz S350, 2013 Mercedes-Benz S500, and 2009-2014 Mercedes-Benz CL550 applications with the specified suspension equipment. It is a practical option for drivers looking for a Mercedes-Benz S-Class coil spring conversion kit that addresses air suspension service needs with a conventional spring-and-shock layout.

What It Helps Address

• Air suspension component wear on Airmatic-equipped vehicles
• Suspension sag caused by aging air springs or related parts
• Ride-height inconsistency from failing air-assisted suspension components
• Repeated air suspension service on W221 chassis models
• Need for a passive coil spring suspension conversion

Installation Notes and Tips

Confirm vehicle equipment before ordering, including Airmatic, ADS, and 4Matic configuration where applicable. This kit is for front and rear conversion on the listed vehicles and should be matched to the exact model and year shown in the fitment data. Professional installation is recommended because suspension conversion work affects ride height, alignment, and overall chassis behavior.
