SHIBATA GRK5 16T Aluminum Bevel Gear – R31S125

The SHIBATA GRK5 16T Aluminum Bevel Gear is a performance drivetrain upgrade designed specifically for the GRK5 and GRK5-R.

SHIBATA developed this 16-tooth aluminum bevel gear to increase secondary reduction for modern RC drift setups that are trending toward higher wheel speed. The goal is to provide stronger speed extension while maintaining controllability through the mid-throttle range. 

Its lightweight aluminum construction also makes it a premium choice for competitive GRK drift builds where drivetrain response and efficiency matter.
