Product snapshot

The Tamiya 95421 6-Spokes Aluminum Ball-Race Rollers are aimed at Mini 4WD racers who want cleaner rolling action. These 19mm rollers use ball bearings to cut friction and support steadier speed through turns.

Construction and performance

Built from machined aluminium for strength and consistent geometry, the rollers take 520-size ball bearings that deliver smooth rotation and dependable behaviour under race loads.

Installation notes

Compatible with Mini 4WD and Mini 4WD PRO chassis types. The set ships with screws and spacers for typical layouts, though a small number of body shells may need trimming or bracket repositioning for ideal clearance.

I have been purchasing Tamiya products with Rcjaz for a couple of months now, selection is awesome and service is quick and reliable, considering I leave half way around the world.

Can I use these on any Mini 4WD body?

They fit most Mini 4WD and Mini 4WD PRO bodies, but tight-fitting shells might require minor trimming to avoid contact with the rollers.

Do the rollers add significant weight?

Aluminium rollers add some mass compared with plastic, but the improved bearing spin and durability often offset the small weight increase for racers.

How do I clean the rollers and bearings?

Remove bearings from the roller, clean with a light solvent, dry fully and apply a drop of light oil before reassembly to maintain free spin.

Are replacement bearings available?

Standard 520-size ball bearings are used, so replacements can be sourced from common RC parts suppliers if needed.

Will these improve lap consistency?

By reducing rolling resistance and smoothing rotation, these rollers can help produce more consistent lap times, especially on technical track sections.
