The Tamiya 95577 13mm Red Aluminum Ball-Race Rollers are a precision option for Mini 4WD constructors aiming for lower drag and smoother spin. Fabricated from aluminium and fitted with 520 ball bearings, these rollers reduce rolling resistance and help preserve momentum on both straights and curves. Their ringless style cuts down on wall contact friction and suits both front and rear fitting positions where 13mm rollers are required.
The red finish provides a clear visual upgrade while retaining toughness for regular use. They are compatible with Mini 4WD and Mini 4WD PRO platforms that accept 13mm rollers. Each set includes two rollers together with the screws and small fixings needed for a standard assembly, allowing quick fitting at the bench or in the pits.
