Precision Aluminium Rollers for Mini 4WD Racing

The Tamiya 95301 Lightweight 13mm Aluminum Ball-Race Rollers are a compact, durable upgrade aimed at improving rolling efficiency. Crafted from aluminium with a ringless design and fitted with 520 ball bearings, they minimise friction when contacting track walls and promote steadier rotation. Suitable for front and rear positions, they support a range of tuning approaches.

These rollers achieve about a 30% weight reduction through a slimmer profile and engineered cut-outs, aiding acceleration and on-line stability. They are compatible with Mini 4WD and Mini 4WD PRO chassis, although certain body styles or older kits may need modest modifications to secure ideal fitment.

How do I check roller alignment after fitting?

Mount the roller and rotate the axle by hand while observing for any side-to-side wobble or rubbing. Use thin spacers to correct offset and ensure even contact with guide rails.

Can these be used with foam or rubber tyres?

Yes, they work with most tyre types. The main consideration is chassis balance and clearance; adjust ride height and roller position to suit your tyre choice.

What routine checks should I perform?

Inspect for bearing smoothness, clean out grit, and reapply a small amount of lubricant. Also check for any deformation in the roller body after repeated impacts.

Do these reduce the need for heavier stabilisers?

Lighter rollers can improve responsiveness, which may allow you to tune with lighter stabilisers. Adjust stabiliser weight based on handling during test runs.

Are replacements for the 520 bearings available?

520 standard bearings are widely available from hobby suppliers if you need spares. Keep the bearing size in mind when sourcing replacements to ensure correct fit.
