This Yokomo D-148 bearing set is intended as a direct upgrade for assembled Drift Racer drift kits, allowing replacement of worn bushings or bearings in wheel hubs and steering support locations. Bearings reduce rotational friction and contribute to improved slide control during practice.
Fitment is a routine model-building job: remove the wheel and steering retainers, press the matching bearings into the hub and support bores, and reassemble with the original screws. If needed, apply a small amount of light grease designed for metal bearings to control axial play, and avoid over-torquing to prevent added bearing resistance.
Note on handling: installing full metal bearings like the D-148 cuts down on wheel slop and refines steering return, which helps with consistent angle management under throttle. Bearings alter rolling characteristics and driver feedback, not motor output or suspension geometry.
