The Shimano Deore RD-M5120 Rear Derailleur Stabilizer Unit consists of the replacement internals for the stabilizer unit on select Shimano rear derailleurs.

If your derailleur has some miles on it or the stabilizer has become damaged, installing this part will restore a rear derailleurs stability and performance.
