RC Outrunner 8mm Shaft Replacement - Scorpion SPHK4035MSK8  [SPHK4035MSK8]

Precision Shaft Replacement for Outrunners

The Scorpion SPHK4035MSK8 shaft kit is a precision replacement part made for RC outrunner brushless motors that use an 8mm shaft. It addresses shaft wear and minor damage that can lead to increased runout and reduced balance.

Use this kit when performing maintenance or a mid-level rebuild to realign rotor and stator and to ensure a stable mount for pinions or other driveline components common to outrunner designs. Always confirm the motor type and that the shaft interface is 8mm before ordering.

Fitment guidance: check bearings and bearing seats for wear before installing the replacement shaft, make certain the shaft sits squarely in the rotor and bearing bores, and recheck axial play and runout after assembly. Secure all retaining hardware to the correct torque and carry out a static balance check prior to running at speed.
