Precision Ball-Race 17mm Rollers by Tamiya 95563

The Tamiya 95563 HG Lightweight 17mm Aluminum Ball-Race Rollers are precision parts aimed at improving the rolling dynamics of Mini 4WD models. Crafted from lightweight aluminium, these ringless rollers balance mass savings with sufficient strength. Each roller is drilled with eight holes to achieve a weight of 0.81 grams per piece, which is around a 0.25 gram reduction per roller versus many standard options, aiding quicker acceleration and reduced rotational inertia.

Built-in 520 ball bearings ensure smooth, low-resistance rotation for better stability and repeatable handling. They are compatible with both Mini 4WD and Mini 4WD PRO chassis, but some vehicles may require small body or mount adjustments to clear the roller assemblies.
