Tamiya AO-1002 Mini 4WD Metal Bearing Set(94381)

A set of four metal bearings for Mini 4WD, sold as a maintenance replacement item for when the plastic bearings or eyelet bushings on a chassis have been lost or worn out. These fit the standard bearing positions used across Tamiya's Mini 4WD chassis lines.

Tamiya catalogues this as an AO Parts item — its aftermarket option-parts line for small maintenance and replacement components rather than full grade-up kits. Several current kits, including the VZ-chassis Iron Beak and Ray Spear, ship stock with plastic 620 bearings moulded in low-friction POM; metal bearings like these are the classic aftermarket step up from that stock plastic, valued for lower rolling friction at the gearbox and axle positions where efficiency losses add up over a race.
