3Racing M4WD-30/LB light blue 13mm ringless aluminum ball rollers for Mini 4WD

These 13mm ringless aluminum ball race rollers from 3Racing are described in Tamiya-compatible terminology and intended as replacement or detail rollers for Mini 4WD hobbyists. The components use an aluminum outer body with an internal ball mechanism; the ringless form factor reduces outside diameter at the contact edge compared with ringed rollers.

Fitment is stated for Tamiya Mini 4WD applications. The rollers are finished in light blue anodizing and are aimed at collectors and builders who want an alternative visual and contact profile without changing chassis layout. The design does not include external retaining rings and requires standard roller mounting hardware used on most Mini 4WD chassis.

Notes for experienced users: the ringless profile alters the contact edge compared with ringed rollers, which can change how the roller interacts with guard surfaces. Observe clearance and mounting orientation during installation. Do not treat these as a substitute for specified race components on series that restrict aftermarket parts.
