For Tamiya Mini 4WD 19mm ringless aluminium ball-race roller M4WD-32/GO by 3Racing  [M4WD-32/GO]

Model M4WD-32/GO is a 19mm ringless aluminium ball-race roller with gold anodize. The slim ringless profile reduces side lip contact and gives a lower visual and physical profile for tight guide clearances. The aluminium shell keeps the roller rigid while the internal ball arrangement lowers rotational friction versus common plastic rollers.

Application is standard for 19mm roller mounts on many Mini 4WD platforms. Installation uses 3mm or 4mm roller shafts with the correct spacers and washers to prevent binding while retaining secure fit. Use as an aftermarket roller on popular chassis where 19mm rollers are specified, including MA, MS, AR, FM-A and Super-II setups.

Finish and machining suit builders and collectors who want a consistent show appearance; the gold anodize hides minor scuffs better than raw metal and the ringless silhouette keeps the roller visually compact from the side. This listing is for the roller only; motors, gears, and chassis parts are not included.
