The AWD-20 bearing set is a compact upgrade for Kyosho Mini-Z AWD drivetrains that replaces friction-prone running surfaces to improve rotation smoothness and deliver more consistent throttle response during track practice.
Designed for platforms using MR-03 AWD style drivetrains, these bearings are intended to replace standard bushings or worn components where dimensions match. Confirm fit against your chassis before final assembly to ensure correct clearance.
Installation notes: fit bearings into the gearbox, hubs and rotating shafts where applicable, checking orientation and free spin as you go. Light, appropriate lubrication for small bearings will prolong service life and preserve low friction.
As a tuning item, this bearing set reduces drivetrain drag so acceleration feels crisper and steering inputs translate more directly on carpet and other slick indoor surfaces. Use AWD-20 as part of a drivetrain refresh when seeking small efficiency gains without changing major hardware.
