M4WD-33/GO 8-9mm double roller upgrade for Mini 4WD

This double roller kit contains two concentric 8-9mm aluminium rollers with a gold anodised finish. Supplied as an aftermarket spare, the components are aimed at Mini 4WD cars compatible with 8-9mm roller assemblies and prioritise solid build quality over speculative performance claims.

For regular hobbyists: the aluminium rollers replace worn plastic parts and provide a stable contact surface where double rollers comply with class rules. Measure rail spacing and confirm side stay clearance before mounting since the stacked design increases overall width and can change interaction with stabilisers.

Typical installation follows standard roller mounting conventions. Match shaft diameter, use low-friction hardware, avoid over-tightening which may distort the thin aluminium walls, and perform periodic checks for wear and burrs.

Do I need new shafts to use these rollers?

If your current shafts match 8-9mm mounting specs and are straight, you can usually reuse them. Replace any bent or excessively worn shafts for best results.

Will these increase cornering stability?

Double rollers can alter handling by changing contact points, but outcomes depend on overall setup. Consider them part of a package of mods rather than a single handling cure.

Are washers or spacers needed?

Spacer stacks are often required to position the rollers correctly. Reuse compatible spacers or select new ones that maintain even clearance and avoid side-to-side play.

How resistant is the gold finish to chipping?

Anodising adheres to the aluminium and resists normal wear, but heavy abrasive contact can wear the finish. Inspect surfaces regularly and remove debris to prolong the coating.

Can these be used on high-clearance builds?

They can be fitted on higher-clearance cars, but check that the increased profile does not snag on track edges or bumpers when the car jumps or leans.
