A rubber composition for an automobile damper is provided to ensure high heat resistance and oil resistance, and excellent mechanical property, and to improve durability and smoother ride of vehicles by minimizing an original oscillation frequency change rate at a high temperature. A rubber composition for an automobile damper comprises (a) fluorinated rubber 100 parts by weight represented by formula 1: (CF2-CH2)X-(CF2-CF2)Y; (b) silica 20~30 parts by weight having particle size of 200~500 nm; (c) an amine-based cross linker 1~1.5 parts by weight; (d) a vulcanization aid 2~3 parts by weight; (e) a softening agent 1~2 parts by weight; (f) a promoter 3~4 parts by weight; (g) activator 2~3 parts by weight; and (h) antiaging agent 3~4 parts.
