Tamiya 95499 13mm Ball-Race Rollers - Racing Upgrade  [95499]

Tamiya 95499 13mm Racing Rollers Overview

The Tamiya 95499 13mm aluminum ball-race rollers are intended to refine Mini 4WD behaviour by lowering rotational drag and cutting unnecessary weight. Equipped with 520 ball bearings, the rollers offer consistently smooth rotation which helps reduce speed loss when the car runs against guide rails.

Suitable for installation at both front and rear mounting points, the rollers use a bored design to shave roughly 30% off the original component mass while maintaining a strong profile. This makes them useful for racers who want to balance lightness with structural reliability.

Included are two 13mm aluminum rollers and the screws needed to mount them, letting you fit the parts quickly. They are compatible with all Mini 4WD and Mini 4WD PRO chassis platforms, although specific chassis shapes or modified bodies may require minor adjustments to achieve a perfect fit.
