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

The M4WD-32/GO is a 19mm ringless aluminium ball-race roller plated in gold. Its ringless edge trims external lip contact for narrower guide setups while the aluminium body increases stiffness compared to standard plastic rollers. Internal ball elements are used to reduce spinning resistance.

Fitment aligns with common 19mm mounting points on Mini 4WD machines. Install using the correct 3mm or 4mm roller shafts and tailor spacers to avoid lateral play and to stop the roller binding on the stay. It is intended as an aftermarket accessory for chassis families where 19mm rollers are used such as MA, MS, AR, FM-A and Super-II.

The anodised gold surface gives a uniform display look and helps hide light marks from handling, making it a sensible pick for display models as well as tuned race cars. Note that no motor, gearset or chassis components are supplied.
