Tamiya Super-II Mini 4WD 19mm Ringless Aluminium Roller Set - M4WD-32/LB by 3Racing  [M4WD-32/LB]

Light blue M4WD-32/LB 19mm ringless aluminium rollers

This 19mm ringless roller set M4WD-32/LB is designed as an aftermarket spare for Tamiya Mini 4WD cars. Each roller is machined from anodized aluminium and prepared for ball bearings, giving a smooth rolling surface for builders replacing worn parts or matching display colours. The ringless profile reduces flange contact with guide rails; confirm clearance on Super-II, MA or MS chassis before final fitting.

Fitment uses common 3mm roller posts and the appropriate bearings or bushings. Being aluminium, inspect rollers after impacts for burrs, avoid over-tightening fasteners that can deform the barrel, and apply a light lubricant to bearing races if reinstalling ball bearings. The light blue anodised finish is cosmetic and will show wear depending on use.

These rollers suit collectors and builders seeking colour-matched spares rather than a chassis performance package; treat them as service items and visual upgrades for 1/32 Mini 4WD runners.
