Kyosho Mini-Z AWD Full Ball Bearing Set by 3Racing AWD-21  [AWD-21]

Mini-Z AWD full ball bearing set

This full ball bearing set is a direct-purpose accessory for Kyosho Mini-Z AWD platforms, aimed at reducing drivetrain friction and improving rotational smoothness in small-scale RC use. It is produced by 3Racing and carries the AWD-21 identifier for easy reference.

Use this set when you want cleaner bearing action in gear trains and wheel hubs on MR-03 AWD style Mini-Z AWD layouts. Installation typically replaces worn or lubricated bushings and stock bearings; careful pressing or gentle seating avoids bearing damage. Regular cleaning and light lubrication help retain performance without over-oiling.

From a tuning perspective, full ball bearings lower mechanical drag and can sharpen throttle response and free up minor power losses at high RPMs, which is useful on short-track or indoor carpet setups where drivetrain efficiency matters more than raw power.
