The Tamiya 94759 JR 19mm Aluminum Ball Race Roller brings a durable and attractive option for Mini 4WD setups where cornering control matters. Constructed from high-grade aluminium with a red dish profile, these rollers balance strength with low weight and pair well with both standard and PRO Mini 4WD models.
Equipped with 520 ball bearings, the rollers cut rolling resistance for a more consistent rotation, which helps with speed retention on bends. The set includes screws, rubber rings, and aluminium spacers so you have everything needed for a quick swap.
