Mini-Z AWD Low-Drag Drivetrain Bearings AWD-20 for MR-03 by 3Racing  [AWD-20]

Mini-Z AWD low-friction bearings

The AWD-20 bearing kit is a simple upgrade for Kyosho Mini-Z AWD drivetrains, targeting friction points in the transmission to improve rotational smoothness and give a more consistent on-track response.

These bearings suit MR-03 AWD style arrangements found in many Mini-Z AWD cars and are intended to replace worn bushings or plain bearings where measurements are compatible. Verify fit before fitting to avoid interference.

Fitting tips: install bearings into gearbox casings, hub bores and rotating shafts as relevant, checking each bearing for free spin after fitting. Use a minimal, suitable lubricant for small bearings to preserve their low resistance.

As a tuning component, the set lowers drivetrain drag so acceleration feels quicker and steering inputs translate more directly on carpet and smooth indoor surfaces. Use AWD-20 when refreshing the drivetrain for modest efficiency improvements.
