Rear Air Suspension Spring for Mercedes-Benz E-Class and CLS-Class

Detailed Description

Arnott A-2724 is a rear air suspension spring built for Mercedes-Benz models that use rear air suspension on the W211 and W219 platforms. It is designed as an aftermarket replacement for OE part numbers 2113200725, 2113200825, 2113201525, 2113201625, and related suffix variants. The spring uses a rubber bellows construction with a convoluted profile, a stud upper mount, and a base cup lower mount for a direct service replacement.

Arnott’s NEW product line focuses on redesigned replacement suspension components that address common wear points in air spring service. For this application, the reservoir has been eliminated to streamline installation and reduce unnecessary complexity. This part cross-references Mercedes-Benz OE numbers 2113200725 and 2113200825 for the same application.

What It Helps Fix

• Rear corner sagging on Mercedes-Benz E-Class or CLS-Class vehicles
• Air leaks caused by a cracked or aging bellows
• Uneven ride height at the rear suspension
• Compressor overwork caused by a leaking air spring
• Ride quality loss from worn rear suspension components
