Mini 4WD Ringless 19mm Aluminium Ball Race Roller M4WD-40/LB by 3Racing  [M4WD-40/LB]

3Racing M4WD-40/LB 19mm ringless aluminium race roller - light blue

The 3Racing M4WD-40/LB is a 19mm ringless aluminium ball race roller presented in light blue. Its ringless profile limits outer diameter and suits compact layouts where minimal protrusion is preferred.

Assess axle spacing, post bore and mounting orientation before installation to confirm correct fit. Test bearing and spacer arrangements to dial in axial play and prevent rubbing on guides or bumpers.

When positioning on MA, MS, AR, FM-A, VS or Super-II platforms, verify roller clearance with any post guards or protectors in place. The ringless outer face will interact differently with guide edges, so alter spacer stacks to match your chassis geometry.

Check packaging information and part colour on receipt to make sure the item matches your requirements before fitting to a race car or display model.
