In order to keep your motor in top running condition, you need a good set of bearings. Occasionally, after a crash or landing in the dirt, the bearings can become damaged and need to be replaced. The Scorpion HK-40mm Motor Bearing Kit includes a pair of original equipment replacement bearings to fit the Scorpion HK-4025 and HK-4035 Series motors.

These bearings measure 16mm OD x 8mm ID x 5mm thick, and are an exact replacement for the stock bearings that come with the motors.
