Racing-grade Mini-Z AWD bearing set

Engineered for competitive Mini-Z AWD setups, this full ball bearing kit targets reduced mechanical drag and improved rotational precision in compact drivetrains. AWD-21 denotes the specific part number for setup and spares.

Fit the bearings to MR-03 AWD style and related Kyosho Mini-Z AWD platforms when seeking lower friction in gear trains and wheel hubs. Use controlled pressing or accurate drivers to seat bearings squarely and avoid misalignment; consistent cleaning and a light high-quality bearing oil maintain peak performance without adding drag.

From a tuning standpoint, low-drag bearings help free up small horsepower losses at high RPM and refine transient throttle response, advantages that translate to more consistent lap times on short indoor circuits and club racing carpets.

Which chassis and hubs use these bearings?

Designed for Kyosho Mini-Z AWD platforms, the kit suits MR-03 AWD style chassis and other AWD Mini-Z formats that share compatible bearing seats.

Recommended installation workflow?

Use precision drivers or a small press, align bearings squarely, check for smooth spin before final assembly, and avoid impact tools that risk brinelling the races.

Maintenance for racing use?

Inspect bearings after heavy sessions, flush to remove contaminants, and apply a thin film of racing-grade micro bearing oil to balance durability and low drag.
