Mini 4WD Colour-Matched 19mm Ringless Rollers for Super-II - M4WD-32/LB by 3Racing  [M4WD-32/LB]

M4WD-32/LB 19mm ringless aluminium rollers in light blue

These 19mm ringless rollers, model M4WD-32/LB, are anodised aluminium replacements for Tamiya Mini 4WD cars. The components are machined for ball bearing fitment to provide steady rotation for builders swapping worn parts or coordinating a display setup. The ringless barrel reduces flange interference with track guides; always verify clearance on Super-II, MA or MS configurations before finishing the install.

Setup uses standard 3mm roller posts along with the appropriate bearings or bushings. As with any aluminium roller, check for burrs after crashes, avoid over-torquing fasteners which can dent the body, and keep bearing surfaces clean and lightly lubricated if ball bearings are used. The light blue anodised finish is decorative and will age with handling.

These parts are intended as practical spares and visual upgrades rather than a comprehensive performance kit, making them a good match for collectors and builders who prioritise appearance and routine maintenance.
