3Racing M4WD-32/GO 1/32 scale, 4WD drivetrain, 19mm ringless aluminum ball-race roller accessory  [M4WD-32/GO]

The 3Racing M4WD-32/GO is a 19mm ringless aluminum ball-race roller finished in gold anodizing. Designed as an aftermarket roller for 1/32 Mini 4WD models, the ringless profile reduces external lip contact and presents a slim, low-profile option for builders who prefer compact roller geometry. The aluminum shell provides structural rigidity while the internal ball arrangement aims to lower rotational friction compared with plain plastic rollers.

Fit and application are typical for standard 19mm roller mount locations on Tamiya Mini 4WD chassis. Installation requires compatible 3mm or 4mm roller shafts and appropriate spacer/washer selection to maintain secure mounting without binding. The part is an accessory component and can be used on performance-oriented chassis such as MA, MS, AR, FM-A and Super-II where 19mm rollers are appropriate.

Finish and machining are relevant to collectors seeking consistent appearance across display models; the gold anodizing reduces visible wear compared with bare aluminum, and the ringless form factor keeps the roller profile minimal when viewed from the side. No motor, gearing, or chassis parts are included.
