Tamiya Mini 4WD 13mm Ringless Ball Rollers - M4WD-30/LB Light Blue by 3Racing  [M4WD-30/LB]

M4WD-30/LB 13mm ringless aluminium ball rollers in light blue for Mini 4WD

These 13mm ringless aluminium ball race rollers are described using Tamiya-compatible fitment language and serve as replacement or cosmetic rollers for Mini 4WD model builders. The parts use an aluminium outer body over ball internals; the ringless form reduces the effective outer diameter at the contact edge versus ringed types, changing the roller contact profile.

Fitment notes indicate compatibility with Tamiya Mini 4WD mounting standards. The rollers are anodised in light blue and are intended for hobbyists seeking a different finish and a slimmer contact edge while preserving factory chassis spacing. No external retaining rings are used, so standard roller screws and spacers common to Mini 4WD are required for installation.

For experienced users: the ringless edge will interact differently with guard surfaces and can alter how the roller negotiates guide rails. Recheck clearances and mounting orientation after fitting, and do not substitute these rollers where competition rules forbid aftermarket items.
