The Tamiya 95301 Lightweight 13mm Aluminum Ball-Race Rollers deliver a low-mass, durable option for Mini 4WD tuning. These ringless rollers are machined from aluminum and fitted with 520 ball bearings to reduce contact friction and promote smooth rolling at speed. They can be used as front or rear rollers depending on your chassis layout and tuning aims.
With around a 30% drop in weight thanks to a refined profile and strategic holes, these rollers help with acceleration and stability through corners. They are designed to work with all Mini 4WD and Mini 4WD PRO chassis, though some vehicles may require slight body or chassis adjustments to fit perfectly.
