Tamiya M4WD-29/GO Golden 9mm Aluminum Ball Race Rollers

The Tamiya Mini 4WD 9mm aluminum ball race rollers, designed by 3Racing, are a compact upgrade for racers who want better cornering stability and smoother rotation. These ringless rollers use durable aluminum with a golden finish to cut friction and keep your speed consistent on technical tracks.

Build and Fitment

The 9mm ball race rollers are compatible with the majority of Tamiya Mini 4WD chassis, making them an easy swap for many setups. The ringless form reduces rotating mass, which helps with acceleration and responsiveness without sacrificing strength.

On-Track Effects

Fitting these aluminum rollers will sharpen handling through bends by lowering contact friction and improving transition control. Racers chasing tighter lap times will notice steadier corner exits and reduced wobble at speed.
