Tamiya Mini 4WD Compatible 13mm Ringless Aluminum Ball Rollers M4WD-30/RE by 3Racing  [M4WD-30/RE]

M4WD-30/RE 13mm ringless aluminum rollers in red

These 13mm ringless aluminum ball race rollers are an aftermarket spare designed for Mini 4WD use. The part is a compact, low-profile roller intended to sit on standard 13mm roller stays used in common 1/32 Mini 4WD layouts. The red-anodized aluminum shell and exposed ball element define both the look and the rolling interface.

Fit and clearance depend on chassis geometry and stay thickness. The roller is suited as a replacement or visual swap for builders and collectors who service Tamiya Mini 4WD cars. Installation uses conventional roller hardware and requires correct spacer and screw selection; mounting screws or spacers are not supplied.

Material and finish follow typical machined aluminum accessory practice, with an exposed ball assembly. The ringless profile changes contact with guide rails and lane walls compared with ringed rollers, so confirm clearances on tuned or low-body setups to avoid unintended contact with bodywork or stabilizers.
