Tamiya 94768 Jr Bearing Roller Spacer - 20pcs pack

This 20-piece Tamiya 94768 Jr Bearing Roller Spacer set gives Mini 4WD enthusiasts a simple way to adjust roller clearance and alignment. The spacers are useful when refining setups for different track layouts and surfaces.

Fitment and roller compatibility

The spacers are suitable for many Tamiya Mini 4WD chassis and pair well with common aluminum ball-race rollers. Known compatible sizes include the 19mm and 17mm aluminum ball-race rollers, among others, letting you match spacer thickness to the roller type in use.

Practical setup notes for racing

Fine-tuning roller spacing can change how the car enters and exits corners and how it maintains speed on straights. Using these spacers helps reduce unwanted lateral movement and ensures rollers stay properly aligned during heats.
