Arnott a2724 or a2725

Good evening friends I am the happy owner of an E55 AMG that said I find myself with a rear airmatic problem Let me explain, I have to change the rear airmatics, I want to buy Arnott, the problem I have knows that I don't understand one thing, they have two references, A2724 without ADS and 2725 with ADS, is it a problem if I buy the model without ADS because I am ordering them, that said, know a friend's store so I can always change them

So my question is the following: someone in the forum to change the rear airmatic in his E55 AMG in Arnott and what reference did you take

Thank you in advance for your answers

The Arnott catalog only shows the A2725 available for the E55. I do not know from where you are getting the A2724 number.
FWIW, I installed a pair of the A2725 air springs in the rear of my car two years ago. PITA to get the lower ends inserted into the alloy control arm. Be very careful when connecting the air lines to the new air springs. Very little room to work and you do not want to cross-thread the fitting.

hi thank you for your answer arnott 2725 corresponds to the e55 with ADS option (sport 1 or sport 2) sporty steering and hard suspension my question is to know if I have the 2724 arnott without ADS will this cause a problem for the car ? I would just no longer have the sport 1 option because the 2724 is basic for the AMG chassis

Here in the US the A2724 is listed as the rear air spring for the non-AMG models such as the E350 and do not have the features the AMG's have. .

Go to the following link, download the .pdf attachment, and learn about the Airmatic suspension.

https://mbworld.org/forums/e-class-w...ml#post9060765

If you have an E55 AMG, you have three modes for the suspension: Comfort, Sport 1, and Sport 2. Comfort mode uses the external air tanks attached to the stock air springs. Using the Arnott air springs, the external air tanks are cut loose, unbolted, and removed from the car. This leaves you with Sport 1 and Sport 2 modes. For the rear of the car, Comfort affects the air springs (by opening a valve to the external air tanks for a softer ride). Comfort, Sport 1 and Sport 2 affect the rear shocks' compression and rebound damping. Read pages 32-39 in the .pdf attachment in the above link.

You want the A2725 air spring. It is a known fit and recommended by Arnott.
