Tamiya 94381 AO-1002 4WD Metal Bearing Set Summary

The Tamiya 94381 AO-1002 4WD Metal Bearing Set is a practical upgrade for Mini 4WD hobbyists who want better rolling efficiency. This pack contains four machined metal bearings that reduce friction compared with stock plastic parts and provide greater wear resistance.

Fitment and Function

These metal bearings are suitable for many Tamiya Mini 4WD chassis and offer a simple swap to raise drivetrain efficiency. Replacing plastic bearings with these metal units helps wheels spin with less resistance and improves straight line speed on the track.

Race Use and Durability

Using metal bearings lowers component wear and extends service intervals, which is useful for frequent racers. The snug fit of the bearings limits axle play and contributes to steadier handling during high speed runs.
