Tamiya 3RACING M4WD-31/RE 17mm Red Ringless Roller Upgrade  [M4WD-31/RE]

Product snapshot for the 17mm Mini 4WD rollers

The Tamiya Mini 4WD 17mm Aluminum Ball Race Rollers (Ringless) in red give racers a dependable way to lower rolling resistance. These rollers are aimed at enthusiasts who want cleaner lines and steadier handling through technical track sections.

Design and chassis compatibility

Manufactured for smooth rotation, these aluminium ball race rollers use a ringless layout to reduce contact friction. That helps preserve speed through transitions. They are compatible with standard Tamiya chassis such as MS, MA, AR and VS, so they slot into many common builds.

Practical impact on lap performance

With reduced drag and improved lateral stability, the 17mm rollers help maintain momentum in tight sequences. They are particularly useful for drivers focused on minimising speed loss while navigating multiple bends in a lap.
