Incomprehensible damper

These days I decided to inspect brake pads, removed a rear wheel and found an incomprehensible rubber on a shock absorber. Does anyone know what it is intended for?

I think it's to stop the wheel moving in further, when driving in terrain.

It is unlikely. This rubber don't touch the wheel in all its positions

It's a mass damper, attached to the damper spring seat, used to absorb vibration and prevent noise intrusion into the vehicle interior.
Its efficacity/effectivness is mostly observed on gravel roads (or on roads paved with granite cubic stones) where the vibrations are with high frequency and short course.

Alex and Lars are correct. It is a tuned mass damper to reduce vibration and NVH however you might not see it on 11 MY cars me thinks.
