Description:
Genuine Mercedes-Benz rear axle overload bump stop / rubber buffer assembly for Actros MP4 Euro 6 trucks. This component (OE A9603233140, casting A 960 323 31 40 /007) is mounted on the rear axle / chassis and limits suspension travel under heavy load, protecting springs, axle and frame from impact. In Mercedes and European catalogues it is listed as "tampon suprasarcina axa spate" (rear axle overload buffer) for Actros MP4.
The part consists of a strong cast-steel arm with two mounting eyelets and an adjustable stud, combined with a heavy-duty conical rubber bump stop at the lower end. The design is specific to Actros MP4 Euro 6 rear axles and can be fitted on either left or right side depending on configuration.
This item was removed from a running Actros MP4 Euro 6 truck and was tested on the vehicle prior to dismantling to confirm correct function. Rubber element remains elastic with no visible cracks or chunking, and the bracket is straight with only minor cosmetic signs of use. The assembly has been cleaned of heavy dirt and checked for damage before listing. It is sold as a used OEM replacement and is supplied exactly as shown in the photos.
