Super-II and MA/MS 19mm Ringless Roller Set for Mini 4WD - M4WD-32/LB by 3Racing  [M4WD-32/LB]

M4WD-32/LB 19mm ringless anodised aluminium rollers

The M4WD-32/LB ringless 19mm rollers are anodised aluminium spare parts for Tamiya 1/32 Mini 4WD models. These machined rollers accept ball bearings to produce a reliable rolling interface for hobbyists replacing old rollers or creating a coordinated colour scheme. Because of the ringless design, flange contact with guide rails is reduced; confirm chassis clearance on Super-II, MA or MS types before completing installation.

Installation calls for standard 3mm roller posts and compatible bearings or spacers. As aluminium components, inspect after impacts for deformation, avoid excessive fastener torque that may crush the roller profile, and keep bearing races clean with light lubrication when necessary. The light blue anodised finish is decorative and may show wear with regular use.

These parts are aimed at collectors and maintainers who want serviceable spares and aesthetic upgrades rather than a dedicated performance conversion.
