Give your Tamiya Mini 4WD a weight-conscious upgrade with the HG Lightweight Aluminum Ringless Ball-Race Rollers. These 19mm rollers are anodized purple and cut roughly 30% of the mass of regular rollers, helping with quicker transitions and steadier cornering. The built-in 520 bearings ensure a low-friction spin for both front and rear positions.
They work with Mini 4WD and Mini 4WD PRO chassis, but some chassis or body shapes may need small modifications for ideal clearance. All small mounting parts are supplied for easy fitting so you can upgrade quickly.
