For anyone tuning a Tamiya M03M, the 3RACING M03M-14 ball bearing kit provides a practical upgrade path. With 14 matched bearings the kit swaps out factory bushes to reduce mechanical resistance and sharpen throttle response.
Sealed bearings keep contaminants out and preserve lubrication, which helps maintain consistent rotation and lowers maintenance frequency. You will notice smoother drivetrain action and less drag under load.
The 3RACING M03M-14 is produced to align with the Tamiya M03M layout for a snug fit and easy fitting. This is a direct replacement style upgrade that works well for hobbyists wanting better handling without extra tuning work.
