3Racing M4WD-11/LB Mini 4WD 4WD roller stopper accessory  [M4WD-11/LB]

3Racing M4WD-11/LB light blue roller stopper for Mini 4WD

This light blue roller stopper from 3Racing is a compact replacement part intended to limit roller movement where rollers meet track fixtures. It is described as a simple accessory for Mini 4WD setups that encounter frequent roller contact; the colour provides an easy visual cue when inspecting front and rear roller assemblies.

The piece is presented as a spare component rather than a tuning item. Hobbyists who maintain multiple cars or keep a small parts inventory will find it useful for routine replacement or for checking wear on roller mounts. No motor, gearing, or chassis modifications are implied or required to use this stopper.
