Performance-Focused Aluminum Rollers for Mini 4WD

The Tamiya 95301 Lightweight 13mm Aluminum Ball-Race Rollers are a practical upgrade for Mini 4WD racers who want cleaner roll and less drag. These ringless rollers are machined from quality aluminum to balance strength and low mass while using 520 ball bearings to ensure consistent, low-friction rotation against track walls. They suit both front and rear roller positions depending on your setup.

Designed with a focus on weight savings, the rollers cut about 30% of the mass through a refined profile and strategically placed holes. That trimming helps lap times and stability under cornering. They are compatible with Mini 4WD and Mini 4WD PRO chassis, though some models may need minor chassis or body adjustments for ideal fitment.

Will these rollers fit my Mini 4WD without modification?

In most cases yes; Tamiya 95301 works with standard Mini 4WD and Mini 4WD PRO frames. Some chassis or body layouts might require small shims or slight trimming to clear bodywork or stay points.

How do 520 ball bearings change handling?

520 bearings reduce rotational friction compared with plain bushings, producing smoother roll and more consistent cornering speed. That helps reduce energy loss when the roller contacts the side rails.

Are ringless rollers suitable for high-speed tracks?

Yes, ringless aluminum rollers like the Tamiya 95301 are often chosen for faster circuits because of their lower mass and reliable bearing action, but check your clearance and balance to avoid unexpected contact.
