The Tamiya 94759 JR 19mm Aluminum Ball Race Roller adds a performance-focused option for Mini 4WD fans wanting better stability and sharper cornering. Machined from quality aluminium, the red dish finish looks the part while standing up to regular track use. It suits a wide range of Mini 4WD kits, including standard and PRO series chassis.
Each roller assembly uses 520 ball bearings to keep rotational friction low, helping the wheel run truer and maintain speed through turns. The package includes the necessary screws, rubber rings, and aluminium spacers so you can fit them quickly and get back on the track.
