This full ball bearing set is offered as a direct aftermarket accessory for Kyosho Mini-Z AWD platforms and is supplied by 3Racing as model AWD-23. Intended for wheel and driveline service points, the kit replaces common pressed or bush-style bearings to reduce friction and improve rotational consistency of axles, hubs and diff components on small-scale racing models.
Installation is aimed at experienced tuners: bearings are pressed into wheels, differential carriers and motor mount locations where applicable. Verify seating depth and runout prior to full assembly to ensure bearings sit flush and spin freely. Correct installation and light lubrication will maintain reliable track performance.
In a tuning context this set reduces drivetrain drag and refines low-speed throttle and steering feedback, helping deliver repeatable rotational behaviour across wheels and diff parts. Use it as a maintenance refresh or a low-drag upgrade during setup changes.
