Tamiya 3RACING M4WD-31/RE 17mm Ringless Racing Roller Set  [M4WD-31/RE]

Technical overview of the 17mm ringless rollers

The Tamiya Mini 4WD 17mm Aluminum Ball Race Rollers (Ringless) in red are engineered to lower bearing contact loss and deliver consistent rolling resistance under load. These rollers are intended for racers refining lap time through small efficiency gains.

Mechanical behavior and chassis integration

The aluminium ball bearings provide predictable spin characteristics while the ringless design reduces surface drag. These rollers integrate with common Tamiya platforms including MS, MA, AR and VS, though precise shaft and spacer alignment is important for optimal performance.

Setup considerations for racing use

Use these 17mm rollers as part of a balanced setup where suspension, weight distribution and tyre choice are tuned in concert. The reduced drag aids corner exits, but small adjustments to roll centre and stabiliser settings may be required to retain neutral steering response.
