Refine drivetrain efficiency with 3RACING 3RAC-3PY/43

The 3RACING 3RAC-3PY/43 aluminium pulley gear is a compact upgrade aimed at reducing drivetrain losses and delivering steadier power transfer. It is intended for RC hobbyists who perform routine upgrades and tuning.

workshop and track use

This component suits both garage rebuilds and trackside adjustments. Its lower mass helps maintain rotational inertia while reducing unnecessary load on gears and bearings.

Fitment overview

Designed to work with a broad range of RC platforms, the 3RACING 3RAC-3PY/43 offers reliable engagement and consistent running. Verify fit dimensions against your chassis before installation to ensure compatibility.

How do I check if it will fit my car?

Measure your current pulley diameter, tooth count and shaft bore, then compare with the 3RACING 3RAC-3PY/43 specifications to confirm fit.

Will this change handling characteristics?

The pulley itself mainly affects drivetrain efficiency; any noticeable handling change will come from altered acceleration or drive feel if gear ratios are adjusted.

What basic care does it need?

Keep the part clean of grit, check for wear at mounting points, and retighten fasteners after the first short run to settle components.
