What is the main benefit of the Gas-A-Just shock absorber design?

The Gas-A-Just shock absorber uses a dual-chamber design. It provides a comfortable ride during normal driving thanks to its high-pressure nitrogen gas chamber, while instantly adding performance on demand when needed.

Why is it important for suspension to work as the manufacturer intended?

Modern vehicles rely on suspension, brakes, and tires working together. Ensuring your suspension operates as designed helps keep electronic safety systems, like stability control, functioning correctly.

Does this shock absorber come with any mounting hardware?

This product includes the KYB Gas-A-Just rear shock absorber. Mounting hardware is not typically included and may need to be sourced separately if your original hardware is damaged or missing.

About this part

Product Details

When it's time to replace the rear shocks on your 2010-2016 Mercedes-Benz E350, E550, or 2010 E63 AMG, the KYB Gas-A-Just monotube shock absorber is a solid option to bring back your vehicle's original capabilities. This shock absorber is designed as a direct replacement, helping to ensure your electronic safety systems continue to function as the manufacturer intended.

The Gas-a-just shock absorber uses a monotube design with two distinct working chambers. One chamber contains an air-free hydraulic piston and valve system for responsive control, while the other has a high-pressure nitrogen gas area with a floating piston. This setup offers a comfortable ride during normal driving, but it can instantly provide improved performance when you need it, like during spirited driving or when carrying a load.
