Kyosho Mini-Z AWD Upgrade ball Bearing Set by 3Racing AWD-20  [AWD-20]

Mini-Z AWD ball bearing upgrade

This 3Racing AWD-20 item is an upgrade ball bearing set intended for Mini-Z AWD platforms from Kyosho, focused on replacing friction-prone running surfaces in AWD drivetrains. The set is designed for hobby-grade Mini-Z use and targets smoother drivetrain rotation and more consistent response on indoor tracks and practice sessions.

Compatibility centers on Kyosho Mini-Z AWD layouts that use MR-03 AWD style drivetrain components. The bearings replace standard bushings or worn parts where applicable, restoring free rotation and reducing power loss through the transmission path.

Installation notes: bearings are installed inside the gearbox, hubs, and rotating shafts where applicable to AWD Mini-Z assemblies. Check fit and orientation during assembly, and verify free spin before final reassembly. Regular inspection and light lubrication suited to small ball bearings will maintain performance over time.

The tuning role of this bearing set is to lower drivetrain drag, which can sharpen acceleration response and make steering inputs feel more immediate on carpet and slick indoor surfaces. Use it as part of a drivetrain refresh or when seeking minor efficiency gains without other hardware changes.
