Arnott has created a completely new advanced Mercedes-Benz front air spring, A-2587, for the Mercedes R-Class. Arnott's exclusive design allows you to economically replace just the dry-rotted air spring portion of your Mercedes R-Class front air suspension strut. Arnott's design features a unique stamped steel upper cap and CNC-machined lower piston. The new Mercedes air spring assembly also includes a new upper mount, air fitting, and internal bump stop. Arnott's aftermarket air spring boasts a more comprehensive design providing your Mercedes with superior strength and handling.
