Mini-Z MR-03 AWD Drivetrain Bearing Set AWD-20 by 3Racing  [AWD-20]

Mini-Z AWD drivetrain bearings

The AWD-20 bearing set is a compact drivetrain upgrade aimed at Mini-Z AWD cars using MR-03 AWD components. It replaces friction-prone surfaces to improve rotational roll and steady throttle response during practice or club racing.

Compatibility focuses on MR-03 AWD style layouts; these bearings serve as replacements for worn bushings or older plain bearings when dimensional match is confirmed. Always test fit to verify clearance and alignment.

Installation pointers: insert bearings in the gearbox, wheel hubs and rotating shafts where applicable, checking for free spin after each fit. Keep bearings clean and apply a light, appropriate lubricant to maintain low friction.

In tuning terms, the bearing set reduces drivetrain drag so acceleration response feels sharper and small inputs transmit more directly on carpet and other smooth indoor surfaces. Use AWD-20 as part of routine drivetrain maintenance or modest efficiency tuning.
