Detailed Description

The Arnott A-3313 is an aftermarket rear right air spring engineered for Mercedes-Benz models that use rear air suspension. It is a direct replacement for applications such as the Mercedes-Benz GLC300 rear right, E-Class rear right, and CLS450 rear right, along with additional AMG and 4MATIC-style fitments listed below. This part cross-references Mercedes-Benz 2133200225 for the same application. The A-3313 part number is also useful when searching for a rear right air suspension spring for Mercedes-Benz GLC-Class X253, E-Class W213, and CLS-Class W257 vehicles.

Arnott’s NEW product line focuses on aftermarket suspension components built with OE-style fitment and upgraded materials where specified. For this air spring, the Continental ContiTech sleeve and reinforced hardware are selected to support consistent air retention and suspension height control in the rear right position.

What It Helps Address

• Rear suspension sag on the right side
• Air spring leaks that trigger ride-height loss
• Uneven stance between left and right rear corners
• Harsh ride caused by a worn air sleeve
• Suspension warning lights related to rear air spring failure

Installation Notes and Tips

Verify the vehicle’s rear right application before ordering, especially on E-Class and E450 models that list front air suspension requirements in the fitment notes. Inspect the air line, fittings, and surrounding suspension components for wear before installation. Confirm that the lower mount type matches the base cup design and that the bellows style matches the original configuration.
