Kyosho Mini-Z AWD Bearing Upgrade Pack AWD-21 by 3Racing  [AWD-21]

Full bearing set for Mini-Z AWD

This full ball bearing pack is offered as an aftermarket upgrade for Kyosho Mini-Z AWD platforms to reduce drivetrain friction and enhance rotational smoothness in small-scale RC cars. The set is identified by the AWD-21 code.

Ideal for replacing worn bushings or stock bearings on MR-03 AWD style Mini-Z AWD builds, these bearings should be fitted with a gentle press or careful hand seating to avoid race damage. Keep bearings clean and use minimal lubricant to sustain performance without attracting debris.

From a setup viewpoint, full ball bearings cut mechanical drag and can improve throttle response and top-end spin efficiency, especially on tight indoor circuits or carpet surfaces where drivetrain losses affect lap time.
