The Tamiya 95612 - 13mm Aluminum Ball-Race Roller is aimed at Mini 4WD enthusiasts who want cleaner rolling and a bespoke colour option. These ringless rollers use sturdy aluminium bodies and 520 ball bearings to cut friction where the roller contacts the track, helping stability at speed. They can be fitted at the front or rear on compatible 13mm roller mounts, offering a straightforward handling upgrade.
The kit contains two 13mm rollers together with screws and small parts for mounting, so installation is quick and user friendly for most racers.
