Lightweight Ringless Rollers - Tamiya 95683 Jr HG 13mm Tapered Aluminum Ball-Race  [95683]

What the Tamiya 95683 rollers bring to your Mini 4WD

The Tamiya 95683 Jr HG Lightweight 13mm Tapered Aluminum Ball-Race Rollers are a straight-to-the-point upgrade for racers chasing lighter rotating parts. The drilled, tapered aluminium bodies lower mass while preserving stiffness for rough use on club tracks.

Materials and riding behaviour

Forged from aluminium and supplied without outer rings, these rollers keep weight down and toughness up. The tapered profile assists re-centering during bends, and the built-in 520 ball bearings keep rotation smooth when approaching tight chicanes.

Compatibility across chassis types

They fit both Mini 4WD PRO and standard Mini 4WD models, letting you test lighter rollers on multiple chassis without buying lots of adapters.

Mass savings and real world effects

Each roller weighs about 0.77 grams, noticeably less than older parts such as Item 95497. The lower mass reduces rotational inertia, helping quicker acceleration and snappier handling out of turns.
