0 A-2724 Arnott New Rear Air Spring Mercedes-Benz E-Class (W211)/CLS-Class (W219) (w/ADS, Excl. AMG) 200

IMPORTANT NOTICE

If replacing an O.E. unit with an Arnott Air Spring, you MUST replace both rear air springs at the same time.

Replacing just one O.E. spring with the Arnott designed air spring may result in a slight difference in heights between the O.E. side and new air spring side. This is due to the vehicle’s ride height sensor reading different pressures in the new and O.E. springs and automatically making adjustments for that. This does not occur if you replace both sides at once.

THE A-2724 ELIMINATES THE NEED FOR AN AIR RESERVOIR.
