Description
The part number A2123267400 is a genuine Mercedes‑Benz OEM kit intended for the rear suspension assembly. It typically includes the dust boot (shock absorber cover) and possibly a bump stop and mounting components, used to protect the rear shock absorber from dirt, debris, and provide correct travel limitation.
-
The boot helps to shield the shock absorber’s piston rod from contamination, reducing wear and extending service life.
-
The bumper or bump stop (if included) prevents the shock absorber from bottoming out under heavy loads or impacts.
-
Correct fitment ensures the rear suspension maintains proper damping behaviour, protection of the shock, and consistent ride comfort and safety.
When the boot is damaged or the bump stop is worn, you may experience premature shock wear, increased ride harshness or unusual suspension noise. Replacing the kit with the proper OEM number ensures correct dimensions, fitment, and materials.
