Tamiya 95563 HG Lightweight 17mm Aluminum Ball-Race Rollers - Performance Ringless Rollers  [95563]

Lightweight 17mm Aluminum Rollers from Tamiya 95563

The Tamiya 95563 HG Lightweight 17mm Aluminum Ball-Race Rollers are engineered to refine your Mini 4WD's rolling efficiency. Built from lightweight aluminum, the ringless rollers strike a balance between lower mass and lasting toughness. Each roller is drilled with eight holes to reach a weight of 0.81 grams per piece, representing about a 0.25 gram reduction per roller versus many conventional rollers, which helps reduce rotational drag on the track.

Each unit includes integrated 520 ball bearings for reliable, low-resistance rotation that enhances vehicle steadiness and response. They fit both Mini 4WD and Mini 4WD PRO cars, though certain body styles may need slight trimming for full clearance.
